Revis has had an MRI that revealed a mild left hamstring strain, coach Todd Bowles said Monday.
Bowles said it's too early to tell whether Revis will be able to play.
"He's a little sore, but he's feeling a little better [than Sunday]," Bowles said. "He hasn't run, so we'll see on Wednesday."
Revis was injured on the first defensive play in the fourth quarter of the Jets' 27-17 loss to the Seattle Seahawks. He didn't return to the game.
The Jets (1-3), losers of two straight, are allowing 285 passing yards per game. Coverage breakdowns have resulted in seven pass plays of at least 40 yards, which has frustrated Bowles, who says it's "way too many."
If Revis can't play, the Jets would have to face the dangerous Antonio Brown with Buster Skrine, Marcus Williams and seldom-used rookie Juston Burris as their top three corners. They also have Darryl Roberts, who has yet to dress for a game. They also could promote Bryson Keeton from the practice squad.
Revis, who brushed off reporters on Monday in the locker room, isn't having a typical season by his standards. He was involved in two long touchdowns in the first two games before settling down in the past two. Despite his inconsistent play, he's still the Jets' top corner. Bowles hinted that he might make lineup changes in the second, though his options are limited.
"We'll look at it and evaluate it day-to-day," he said. "It's a different guy each time [making a mistake]. Things will be shaken up as we go forward."
