The club said that nose tackle Alameda Ta'amu , who tore his ACL in the final game last season, has also come off the list.
Mathieu is coming back from surgery to repair a torn ACL and LCL.
The player widely as the ''Honey Badger'' was having a standout rookie season when he tore the ACL and LCL in his left knee against St. Louis on Dec. 8. In 13 games, he had 62 tackles, a sack, two interceptions, four tackles for loss, a forced fumble and a special teams tackle.
Mathieu has worked out on his own and expressed confidence recently that his knee is sound.
