Revis needs to be cleared for physical activities before he can practice or play.
Coach Todd Bowles confirmed Monday during a conference call that Williams injured the medial collateral ligament in one of his knees and is "day to day."
If Revis can't play Sunday, it would eliminate a potential showdown with the Giants' Odell Beckham Jr., an elite cornerback-wide receiver matchup that fans have been waiting for since the schedule came out.
NEW YORK (AP) — New York Jets cornerback Marcus Williams has a sprained knee ligament that could keep him out against the Giants next Sunday,cheap nfl jerseys.
"We'll see what kind of progress he makes during the week," said Bowles, who didn't rule out Williams being ready in time to play.

Williams was injured when he returned an interception, his team-leading fifth of the season, in the first quarter against the Dolphins.
