A source familiar with the negotiations reports the contract could be worth up to $3 million.
We reported earlier in the middle of the week that he had met with the team and was awaiting an offer. Tollefson, 29, spent the past five seasons with the New York Giants, where he played a part in their winning two Super Bowl titles.
He was a hybrid defensive lineman for Big Blue and rotated from defensive end and tackle.
The 6-4, 266-pound Northern California native has appeared in 57 games (just two starts) and amassed 77 total tackles, 10.0 sacks and three forced fumbles over the last four years. Tollefson proved to be an overlooked and versatile piece of the team’s pie along its ferocious defensive line. He collected 21 tackles, one forced fumble and 5.0 sacks during the Giants’ Super Bowl run in 2011.
A former member of the Raiders’ practice squad, Tollefson, 29, looks to become the third defensive end on the team behind Lamar Houston and Matt Shaughnassy, as he fills in for Jarvis Moss (free agent) and Trevor Scott (signed with New England Patriots).
