FOXBOROUGH, Mass. -- 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. The Patriots said only that he had a knee injury and did not practise Wednesday.

His agent, Sean Kiernan, has not returned an e-mail seeking comment.

On Tuesday, coach Bill Belichick said he didn't think Mayo's injury was season-ending.
