FLORHAM PARK, N.J. -- Star cornerback Darrelle Revis sustained a mild concussion Sunday, the New York Jets announced Monday, and his status for Sunday's game against the Pittsburgh Steelers is uncertain.
"He seems to be feeling good, but whatever those (baseline test) scores are, apparently that's low," coach Rex Ryan said. "I'll lean on the doctors and trainers. We'll see how he progresses during the week."
Revis was hurt on a fluke play in the fourth quarter of the Jets' 48-28 win over the Buffalo Bills. He was chasing running back C.J. Spiller and landed on his stomach after a diving attempt to tackle him. While on the ground, he was accidentally kicked in the head by linebacker Bart Scott, who also was in pursuit.
Revis took a few moments to get up and walked slowly to the sideline, where he was checked for a concussion by the medical staff. He didn't return to the game.
Later, Revis was in the locker room, chatting with teammates, but he didn't speak with the media. The team, citing the league's media policy for players with head injuries, declined to make him available to speak.
Revis also will be off limits on Monday, the team said.
After the game, Revis was fine, according to a source, but the concussion diagnosis was made Monday morning, Ryan said.
Concussions are a hot-button issue, and the league has directed teams to be cautious with head injuries. Ryan said he will "err on the side of caution," relying on the medical staff. NFL protocol doesn't preclude Revis from playing this week, but he must pass concussion tests before he's cleared.
Revis, widely regarded as the best cornerback in the league, set up the Jets' first touchdown Sunday with an interception. He also shut down Bills wide receiver Stevie Johnson, the only player last season to beat Revis for a touchdown.
The Jets would miss him enormously against the Steelers, who have three fast receivers -- Antonio Brown, Mike Wallace and Emmanuel Sanders. Nickel back Kyle Wilson, who also had an interception in the opener, likely would start in Revis' spot.
