ALAMEDA -- The Raiders on Thursday placed defensive tackle Richard Seymour on season-ending Injured Reserve, with one game to play.
The seven-time Pro Bowler has missed the last seven games with a hamstring injury and, given that he restructured his contract last spring, Seymour is due to become an unrestricted free agent and has probably played his last down with the Raiders.
His acquisition from New England by the late Al Davis for a first-round draft pick on the eve of the 2009 season was supposed to revamp a moribund franchise. And while Seymour was selected to a pair of Pro Bowls in Oakland, the Raiders' record in his four seasons were 5-11, 8-8, 8-8 and 4-11 and counting.
If Seymour, 33, is gone next year, he should have a salary cap number of at least $5.26 million in 2013 against the Raiders, due to his remaining $6.575 million guaranteed base salary for 2012 reportedly converted into a signing bonus to be spread over five seasons, for cap purposes.
His cap numbers for the next three years by staying in Oakland would reportedly jump from $17.818 million to $19.133 million.
In 53 games with the Raiders, Seymour has 18 1/2 sacks, with a high of six in 2011 and a low of three this season, with one forced fumble and two fumble recoveries. The eight games played this season is also a career low as his previous low was nine in 2007.
Still, last week Seymour told reporters he could still play at an "elite" level.
