San Francisco 49ers: For the second time in less than a week, the 49ers on Monday added veteran depth to the secondary, signing free agent safety Scott Frost to a one-year contract. The deal is for a base salary of $530,000, the minimum for a veteran with five years of accrued league tenure.

The 49ers last Friday reached agreement with five-year veteran cornerback Fred Weary, also on a one-year contract. Frost, 28, worked out for San Francisco officials last week, along with a number of other free agent defenders, and had an impressive audition.

Best noted for a college career in which he played quarterback at Nebraska, he was chosen as a safety by the New York Jets in the third round of the 1998 draft. Frost played three seasons for the Jets, moved to the Cleveland Browns in 2001 and then to Green Bay in 2002, where he spent the entire season on injured reserve with a shoulder injury.

Frost has appeared in 55 games and started one, and has 37 tackles, one interception, three passes defensed and one sack. He also has 43 special teams tackles for his career.

Buffalo Bills: The Bills added experienced depth on the offensive line, acquiring two-year veteran guard Ross Tucker, released by the Dallas Cowboys early this month.

Tucker, 24, started the final seven games for the Cowboys at left guard in 2002, replacing injured star Larry Allen in the lineup. He performed well and it was regarded as at least a mild surprise when the Cowboys released him two weeks ago.

The former Princeton star, who can also play tackle, originally entered the league with the Washington Redskins as an undrafted free agent in 2001. He appeared in three games for the Redskins in both 2001 and 2002 before his release.

Denver Broncos: Wide receiver Adrian Madise, the latter of the Broncos' two choices in the fifth round of the 2003 draft, has signed his first NFL contract.

The former TCU standout, the 158th player chosen overall, signed a five-year contract that is worth $2.105 million. The deal includes a signing bonus of $190,000 and rookie minimum base salaries of $225,000 (2003), $305,000 (2004), $380,000 (2005), $460,000 (2006) and $545,000 (2007). The deal is unusual in its length, since most players chosen after the second round sign just three-year contracts. There are escalators which can boost the base salaries in 2006 and 2007.

Madise, 23, played two seasons at TCU, starting in 18 of 22 games. He had 82 catches for 1,343 yards and seven touchdowns. The rookie has demonstrated good quickness in mini-camps and earned very good reviews from the Denver coaching staff.

He is the first of Denver's 10 draft choices to agree to contract terms.

New York Giants: The Giants have reached a contract agreement with Radell Lockhart, one of the top defensive ends in the NFL Europe League this spring, and one of just a handful of standout free agents from the springtime loop. Lockhart, 24, had 25 tackles, six sacks and 10 pass deflections playing for the Scottish Claymores this spring.

The former Catawba College star was in training camp with the New England Patriots last summer, had two sacks in the preseason, and nearly made the practice squad. Since last summer, Lockhart has added about 25 pounds to his frame. Given the Giants' need for defensive line depth, he could have a shot at landing a backup spot.

Green Bay Packers: Green Bay has claimed kicker Owen Pochman, recently released by the Giants, on waivers. While he isn't likely to challenge incumbent Ryan Longwell for the No. 1 kicking job, Pochman will provide an extra leg in camp and might be considered for the team's kickoff duties.

The former Brigham Young star handled kickoffs for the Giants for 10 games during the 2001 season. He went to camp last year projected as the Giants' starting kicker, but then suffered a knee injury, and spent the entire season on injured reserve.

A seventh-round pick of the New England Patriots in the 2001 draft, Pochman was cut just before the start of that season and claimed by the Giants on waivers. He attempted two field goals in 2001, of 53 and 66 yards, and missed both.

Pochman became expendable this spring when New York, which overhauled its special teams units, signed veteran kicker Mike Hollis as an unrestricted free agent. The Giants also still have Matt Bryant, who converted 26 of 32 field goals in 2002, under contract.

Miami Dolphins: The Miami Dolphins signed tight end Donald Lee to a four-year contract on Monday.

Lee is the second of this year's draft picks to sign with the Dolphins. He was chosen in the fifth round, No. 156 overall.

Lee started 30 of 45 games in his college career at Mississippi State. He had 22 catches for 161 yards and one touchdown last season. He is the fifth tight end on the Dolphins' depth chart.
