John Clayton takes a look at injuries around the NFL heading into games this weekend:

New York Giants:
The Giants expect to have a new look at cornerback when they step on the field Sunday against Kansas City. Jason Sehorn, recovering from knee surgery during training camp, will make his regular-season debut. Though no official announcement has been made, it looks as though first-round draft choice Will Allen will be the other starter ahead of veteran Dave Thomas. Where does that leave Thomas? Good question. Emmanuel McDaniel is the third cornerback and third-round choice Will Peterson expects to get some playing time. The Giants probably won't deactivate Thomas because he's too valuable on special teams. As for wide receiver Ike Hilliard, he'll miss his second consecutive game. Hilliard was able to test his toe injury only one day this week and it didn't go well. He was limited in practice Friday. Despite being listed as questionable, Hilliard isn't expected to play.

Dallas Cowboys:
With Quincy Carter unable to practice because of the injury to his right thumb, Cowboys coach Dave Campo had no choice but to announce Anthony Wright as his starter for the game Sunday against the Chargers. Carter probably will have to be the third quarterback because Clint Stoerner took all the snaps as the backup. Carter becomes the fourth injured Cowboy to be scratched from the game, joining defensive end Ebenezer Ekuban (back), linebacker Orantes Grant (ankle) and tight end James Whalen (Achilles).

Oakland Raiders:
The Raiders are reasonably healthy heading into their key AFC showdown against the Dolphins. Defensive tackle Roderick Coleman plans to return despite a torn pectoral muscle and should start. Right tackle Lincoln Kennedy will play despite a shoulder injury that should nag him for weeks. Center Barret Robbins will play despite a thumb injury. The only missing starter is defensive tackle Darrell Russell, who is on a four-game substance abuse suspension.

Miami Dolphins:
All seven Dolphins who were listed as probable because of injuries practiced Friday and should be available. That means coach Dave Wannstedt also will have wide receiver Dedric Ward on the active roster Sunday for the game against the Raiders. Wide receiver James McKnight plans to possibly tape a couple fingers together because of a cut between fingers. That won't stop him from playing another important game in the Dolphins' early schedule. The only scratches are defensive tackle Tim Bowens (knee) and backup safety Trent Gamble (shoulder).

Atlanta Falcons:
The Falcons got pretty beat up in their opening loss to the 49ers, but the time off might have help them more than any other team in the league. Even rookie right guard Kynan Forney has a good chance to start despite a big toe injury that would have kept him out last week. Coach Dan Reeves will make a game-day decision on Forney. If Forney can't go against the Panthers on Sunday, Reeves would move Travis Claridge from right tackle to right guard and probably start Ephraim Salaam at right tackle. The time off allowed defensive tackles Edward Jasper, who has a brace on his right knee, and Travis Hall (ankle) to return to close to full strength. Free safety Ronnie Bradford, who missed the opener with an ankle injury, will also return to the starting lineup. Backup cornerback Conrad Hamilton is the only player who will miss the game with an injury. He has a hamstring pull.

Philadelphia Eagles:
Eagles coach Andy Reid will take defensive end Ndukwe Kalu and wide receiver Freddie Mitchell to Seattle for the game Sunday against the Seahawks and make a decision that day on whether to keep them on the 45-man active roster. Kalu, who has an ankle injury, has the best chance of playing. He's been doing full practices for a couple of days. Mitchell, who has been limited in practices because of a hamstring injury, did more Friday than the previous days.

St. Louis Rams:
The Rams will have Grant Wistrom back as the starting defensive end for the NFC West matchup Sunday against the 49ers. Wistrom missed the opening victory over the Eagles and was replaced by Sean Moran. The other good news for the Rams is that Kurt Warner took the wrap off his injured right thumb and had a couple of great throwing days. Linebacker Mark Fields will wear a protective device around his sore ribs and will play. With the Rams having a healthy defensive line, don't be surprised if first-round draft choice Ryan Pickett is on the inactive list. He's currently the fifth defensive tackle. The Rams will probably have eight defensive linemen active for the 49ers game.

Tennessee Titans:
Titans coach Jeff Fisher said unless there is a miracle, quarterback Steve McNair won't play against the Jaguars on Sunday. McNair's right shoulder swelled up after a hard hit in the opening loss to the Dolphins. Neil O'Donnell will start. The only debate is whether McNair or Billy Volek will handle the backup duties. McNair has had two MRIs that showed no structural damage. Still, McNair hasn't had the strength to throw for the past 11 days. Safety Blaine Bishop will play despite a chest injury that has him listed as questionable. Bishop practiced the past two days. Even though cornerback Andre Dyson returned to practice Thursday and started to run, he is probably a week away from being ready to play.

Baltimore Ravens:
Ravens receiver Jermaine Lewis probably will miss the chance to go against the struggling Bengals' special teams because of a strained hamstring from practice Thursday. Coach Brian Billick downgraded him to doubtful. Billick didn't immediately name a new kick-returner, but will have his choice between Corey Harris, Duane Starks and Brandon Stokley. Rookie Gary Baxter has recovered from his knee injury, but he might not be needed Sunday. Since the opener, the Ravens signed safety Carnell Lake to be added to the nickel defense.

Kansas City Chiefs:
The Chiefs plan to go without wide receiver Derrick Alexander in order to rest his Achilles tendon that has been bothering him for weeks. Chris Thomas will start on the other side of Marvin Minnis. Friday, the Chiefs added cornerback Ray Crockett to the injury report because of an ankle injury suffered Thursday in practice. Crockett practiced Friday and was fit enough to start, as was cornerback Eric Warfield, who was listed as probable because of an ankle injury. The Chiefs will have center Casey Wiegmann back in the starting lineup. He had an appendectomy a couple of weeks ago.

New York Jets:
The Jets got good news when Laveranues Coles returned to practice Friday after spraining his foot during the final part of practice Thursday. Herm Edwards said Friday that Coles will be healthy enough to start against the Patriots on Sunday. The Jets, for cap purposes, are going into this game with only 51 players on their roster. The Patriots are starting four former Jets on defense whose average age is 33. A fifth, linebacker Willie McGinest, started in the opener ahead of injured Willie McGinest.

New England Patriots:
The Patriots might indeed have five former Jets starting, but the Jets won't know until game time. Willie McGinest was added to the Patriots' injury list Friday because of a leg injury. McGinest, who had been recovering from back surgery, is listed as probable. It looks as though rookie Richard Seymour, a defensive tackle, will be able to make his New England debut despite a leg injury that sidelined him for the opener. Of the four players listed as questionable, only cornerback Otis Smith is the least likely to play because of a leg injury. Coach Bill Belichick said his chances of playing are slightly less than 50 percent.

Carolina Panthers:
Tim Biakabutuka continues to run with the Panthers' first-team offense, but the competition continues to build. Rookie Nick Goings could take over at some point of the Panthers' game against the Falcons on Sunday if Biakabutuka struggles early. Richard Huntley has recovered from his hamstring injury and might play, but he isn't expected to get too many carries. Huntley had only 10 days of training-camp practice before his injury and is still learning the offense. The Panthers won't have safety Mike Minter and wide receiver Patrick Jeffers because of knee injuries. Center Jeff Mitchell had a scare this week because of an infection because of turf burns, but he should be ready to play.

Cincinnati Bengals:
Bengals coach Dick LeBeau said defensive end Vaughn Booker will start despite a thigh injury that has him listed as questionable. Guard Victor Leyva was downgraded from questionable to doubtful for the game Sunday against the Ravens because of an ankle injury.

Jacksonville Jaguars:
Center John Wade continues to practice despite a foot problem, but it doesn't look as though he will be healthy enough to take the starting job away from Jeff Smith for the Jaguars. Defensive end Tony Brackens (knee) and safety Donovin Darius (hip) are out for the crucial game Sunday against the Titans.

Detroit Lions:
Lions right tackle Aaron Gibson will play despite a sprained foot that forced him to leave practice early Thursday. Though it will be a game-time decision, it doesn't look good for wide receiver Herman Moore, who has missed four days of practice because of a hamstring injury. The Lions decided to downgrade him to questionable. While Moore hasn't practiced, backup receiver Larry Foster has. Foster's return could give the Lions and new quarterback Ty Detmer a little more speed. Safety Ron Rice (toe) and backup cornerback Robert Bailey (ankle) also are expected to return after missing the opener. The Lions will bus to Cleveland on Saturday.

Cleveland Browns:
Browns coach Butch Davis officially scratched wide receiver Dennis Northcutt from the game Sunday against the Lions. He has a fractured clavicle. He will join defensive end Courtney Brown (knee) on the inactive list Sunday. Guard Tre Johnson remains questionable with a finger injury. He practiced a little Friday.

Seattle Seahawks:
The Seahawks won't have cornerback Shawn Springs (hamstring), but they should have Ike Charlton available. Charlton is coming off a knee injury and might just handle backup duty. Against the Eagles on Sunday, the Seahawks might start rookie Ken Lucas and Paul Miranda for a second consecutive game.

Indianapolis Colts:
The Colts officially ruled out backup linebacker Sean Harris with neck and shoulder problems.

Arizona Cardinals:
The Cardinals all but ruled out wide receiver Rob Moore with a hamstring injury. He has been listed as doubtful, but is the only Cardinal on the injury report.

Buffalo Bills:
The Bills' ability to stop Colts halfback Edgerrin James got a boost Friday when defensive tackle Pat Williams returned to practice. He hurt an ankle Thursday and was immediately listed as questionable. With the loss of middle linebacker Sam Cowart for the season, the Bills would have no chance to stop James. The Bills, in fact, are using three difficult linebackers for Cowart's role in the middle of the defense. The rest of the injury report is pretty clean. Defensive end Bryce Fisher will play despite a hand injury.

Chicago Bears and Minnesota Vikings:
The healthiest game involves the Vikings and Bears. The Bears have no injuries and have Marcus Robinson back in the starting lineup. The Vikings have three injured defensive players, but all practiced Friday and will play. They had linebacker Patrick Chukwurah (ribs), cornerback Robert Tate (shoulder) and free safety Orlando Thomas (ribs) banged up, but they will all play.
