Patriots linebacker Jerod Mayo is wearing a brace on his injured right knee and walking with crutches.

Last year's NFL Defensive Rookie of the Year walked through New England's locker room and into the training room on Thursday.

He did not talk with reporters.

Mayo sprained the medial collateral ligament in the first quarter of Monday night's 25-24 win over the Buffalo Bills and could miss up to eight weeks, the Boston Globe reported.
