Mason was on Washington's roster for the first six weeks or so of the season, but they chose Quinton Ganther over him in October. He doesn't do anything particularly well and is now No. 3 behind Rock Cartwright and Ganther.

Dallas is thin because Alan Ball has taken over as the club's starting free safety with Ken Hamlin (high ankle sprain) out indefinitely. Gordon, 26, knows Wade Phillips' scheme and can immediately step in as a dime corner.

Rossum, signed five weeks ago as return help, was hurt for the entirety of his stay on the roster. Patrick Crayton has settled in as the team's punt returner, with Felix Jones on kicks. Rossum, 34, is at the end of the line.

Williams was a special teamer and backup to Mike Sellers. It's not a big loss, but the Redskins' mile-long injury list is getting almost comical. Williams will try to get healthy enough to compete for a spot in 2010 training camp.

It's a reward for the core special teamer's solid play. The extension could push to $1.5 million, but Alexander would have to earn more defensive playing time to earn the incentives.

Brown may have required surgery. He hadn't played in several weeks, although the extent of his injury was never clear. Jon Alston will finish out 2009 as the Raiders' starting strong-side linebacker. Brown will be only 26 next season and figures to re-sign with Oakland to compete for a starting role.

Federkeil was nothing more than a deep reserve. He'll be a restricted free agent after the season.
