Arizona's seven-time Pro Bowl wide receiver Larry Fitzgerald says his injured left knee is "a little bit better" and that he "remains optimistic" he will be able to play when the Cardinals face the Seahawks in Seattle on Sunday.

Fitzgerald sprained his left MCL in last Sunday's 14-6 win over Detroit. He left the game in the first half, but returned and caught a pass for the first down that clinched the victory.

He has started 71 consecutive games, the longest active streak among NFL wide receivers, but coach Bruce Arians said Wednesday that it was "a little iffy" whether Fitzgerald will be able to go against the Seahawks.
