FLORHAM PARK, N.J. -- New York Jets coach Rex Ryan said he "doesn't feel great" about injured defensive linemen Mike DeVito and Kenrick Ellis, and added that if his team were playing the Buffalo Bills on Saturday, both probably wouldn't play.

"This one could drag out until game time," Ryan said. "This one really could be a game-time decision for both of these guys."

Both were limited for a second consecutive practice Friday, and were listed as questionable on the injury report for Sunday's crucial AFC East matchup in Buffalo (5-2). DeVito is dealing with a sprained knee, while Ellis has been bothered by a sprained ankle.

DeVito, one of the Jets' best defenders against the run, practiced for the first time in two weeks Thursday. Hurt in practice, he missed the Jets' previous game, a 27-21 win over the San Diego Chargers, and used the bye week to rehab his injury. Ellis was hurt in the first quarter of the Chargers game.

With DeVito and Ellis banged up and potentially out, the Jets (4-3) have only five defensive linemen.

Wide receiver Plaxico Burress, who has been dealing with lower back stiffness, also was limited Friday and is listed as questionable.

"He's sore, so we limited him [Friday]," Ryan said. "You think he'll be fine but sometimes those backs are troublesome, so hopefully he's feeling good and can play on Sunday."

Burress has been receiving heat treatment for his back ailment.

Cornerback Isaiah Trufant is listed as questionable with a hamstring injury.
