While the Raiders did nothing in terms of slapping a franchise or transition tag on one of their 17 unrestricted free agents by Monday's deadline, they did find some salary cap relief in advance of the new league year beginning March 12.
Right guard Mike Brisiel has restructured his contract, moving his base salary for 2013 from $4.35 million to $1.35 million. The move, first reported by the Bay Area Sports Group, should get the Raiders close to $1.5 million under the cap of $123 million as general manager Reggie McKenzie continues to work to find more breathing room.
Brisiel will receive a $3 million guaranteed roster bonus next week, according to the Associated Press.
In terms of dollars and length, Brisiel was the Raiders' biggest free-agent signing last year. But the zone-blocking specialist played through injury and was largely ineffective before undergoing what McKenzie called "major surgery" on an ankle after the season finale. Brisiel was due to make $3.85 million in base salary in 2014, 2015 and 2016 and had a cap number of $5.06 million for 2013, before the restructure.
He will be pushed this year, though, with the ZBS being scrapped in favor of more power blocking and the emergence of Lucas Nix and Tony Bergstrom.
