Vilma, who was hurt in New York's loss at Cincinnati last Sunday, missed practice all week and was listed as out on the team's injury report Friday. The exact nature of the injury wasn't immediately known or to which knee.

The linebacker underwent several tests during the week and sought multiple medical opinions before deciding to end his season. He's still mulling his options regarding treatment.

Since being chosen in the first round in the 2004 draft, Vilma has played in every Jets game and started all but two. After establishing himself as one of the best playmaking linebackers in the league during his first two seasons, Vilma has struggled to be as effective in coach Eric Mangini's 3-4 defensive scheme. He's fifth on the team with 39 tackles.
