San Francisco 49ers: Former Nebraska quarterback Scott Frost has signed a one-year contract with the San Francisco 49ers.

Frost, 28, a free-agent safety who worked out with the team last week, signed a contract Monday.

As a college quarterback, the 6-foot-3, 218-pound Frost led the Nebraska Cornhuskers in 1998 to a co-National Championship. As a senior, he set school records for quarterbacks for most carries (176), rushing yards (1,095) and rushing touchdowns (19) in a season.

The Jets originally selected him in the third round of the 1998 draft and converted him to safety. He spent his first three NFL seasons in New York before being waived and claimed by the Cleveland Browns, with whom he appeared in 12 games.

Released by the Browns, he was acquired by Green Bay late in the 2001 season. He spent the 2002 season on injured reserve with a shoulder injury.

He also helped coach the Nebraska football team for its bowl game last December after three assistant coaches were fired.

Curtis out four months: Safety Kevin Curtis will miss at least four months, and possibly the entire 2003 season, after re-injuring his knee during a recent mini-camp workout. A fourth-round pick in the 2002 draft, the former Texas Tech standout was sidelined for his whole rookie year when he tore the anterior cruciate ligament in his left knee last preseason.

Curtis tore the same ligament in the mini-camp earlier this month, an MRI examination revealed, and he has already undergone surgery to repair it. The rehabilitation process figures to be a lengthy one.

Team officials have conceded Curtis will miss all of training camp and there is not clear timetable yet for his possible return.

In a roster move, the 49ers have signed free agent offensive lineman Dwayne Ledford, who was one of the top blockers in the NFL Europe League this summer. Ledford had been with the 49ers in training camps in 1999 and 2000. He started at left tackle for the Rhein Fire this spring.

Jacksonville Jaguars: The Jags on Thursday continued to fine-tune their roster as the beginning of training camp approaches, signing unrestricted free-agent offensive lineman Sammy Williams, and also releasing five players.

The most prominent player cut was three-year veteran Ainsley Battles, who appeared in 29 games with 15 starts for the Jaguars over the last two seasons. Battles was acquired via waivers from Pittsburgh in 2001 and had 89 tackles, three interceptions, one sack and nine passes defensed. The other veteran waived was linebacker Jeff Kelly, who had been with the Atlanta Falcons earlier in his career, and was signed just last month.

Two rookies signed as undrafted free agents, kicker Damon Duval and offensive lineman Alex Johnson, were released, as was wide receiver Henry Douglas, on the practice squad for the Jags most of the 2002 campaign.

Williams, 28, provides the Jaguars another veteran offensive linemen with versatility, as he has played both guard and tackle in his career. The former Oklahoma star has been with the Baltimore Ravens, Kansas City Chiefs and San Diego Chargers, appearing in 29 games with 14 starts. He started seven games for San Diego last season.

Tampa Bay Buccaneers: For now, at least, starting tailback Michael Pittman remains a free man.

A probation revocation action originally scheduled for Wednesday was moved to July 2 -- the result of a scheduling conflict with Pittman's attorney. Prosecutors were expected to argue Wednesday that Pittman violated his three-year probation by being indicted on charges of aggravated assault.

Tempe prosecutor Robert Hubbard still intends to argue that the indictment should nullify the probation and, if the court agrees, Pittman could be jailed.

A five-year veteran who led the Bucs in rushing last season, Pittman pleaded not guilty Thursday to two counts of aggravated assault stemming from a May 31 incident in which he allegedly rammed his Hummer into his wife's car. Melissa Pittman has opted not to press charges, but the state decided to pursue the matter anyway.

Each assault charge carries a mandatory jail sentence of at least five years. Pittman almost certainly faces sanctions by the NFL -- even if he pleaded guilty to lesser charges -- since his actions will have violated the league's personal conduct policy.

Neither the Bucs nor the NFL are likely to take action until the charges against Pittman are resolved. Pittman has continued to practice with the team. The Bucs last week acquired former Cardinals first-round tailback in a trade for wide receiver Marquise Walker. The deal was made, in part, to provide Tampa Bay with insurance in the event that Pittman is suspended for a portion of the 2003 season.

Houston Texans: Three-year veteran Pat Dennis, who was to have competed for the starting free safety job in the Houston Texans' secondary, will likely miss all of training camp.

Dennis will undergo a second surgery on his left knee, which he originally last season, and which limited him to three appearances. Dennis tore the anterior cruciate ligament in his left knee last fall and the knee continued to cause discomfort during the team's mini-camp this week.

The former Kansas City and Dallas backup had been working at safety after spending his entire previous career at cornerback.

Washington Redskins: In an effort to fill out their training camp roster, and perhaps find a player or two who might be able to contribute on special teams, the Redskins have signed four unallocated players from the NFL Europe League. The quartet includes Frankfurt safety Rashidi Barnes, the most valuable defensive player from the 2003 spring season.

Barnes and two of the three other additions, defensive end Jonathan Brown and corner Jordan Younger, both of Amsterdam, were among the handful of players cited earlier this week by ESPN.com as viable free agents who could end up in NFL camps. The fourth player signed by the Redskins is Amsterdam cornerback Fred Booker.

In earning defensive MVP honors, Barnes had 45 tackles, four interceptions and eight passes defensed. Brown, a former third-round choice of the Green Bay Packers, posted 6 ½ sacks. Younger likely will be used as a return specialist.

Atlanta Falcons: The team has signed a trio of draft choices - wide receiver Jon Olinger (No. 5), safety Waine Bacon (No. 6b) and defensive lineman Demetrin Veal (No. 7) - to three-year contracts. All three will receive rookie minimum base salaries of $225,000 (2003), $305,000 (2004) and $380,000 (2005).

Olinger received a signing bonus of $110,000, while Bacon got $58,075 and Veal got $31,000 in upfront money.

The deals mean the Falcons have now signed four of the six players they selected. The only unsigned rookies are second-round cornerback Bryan Scott and fourth-round fullback Justin Griffith. Atlanta did not have a choice in the first round.
