ARLINGTON -- The Cowboys lost Mike Jenkins, Jason Witten and Dez Bryant in the fourth quarter of their 27-20 loss to the Chicago Bears on Sunday at Cowboys Stadium.

The biggest injury surrounds starting cornerback Jenkins, who suffered a right knee injury.

X-rays at the stadium were negative, but Jenkins is scheduled to undergo an MRI on Monday. The Cowboys initially diagnosed the injury as a bruised knee.

Jenkins was injured when he was getting blocked by Bears wide receiver Johnny Knox on a 38-yard pass play from Jay Cutler to Devin Hester.

Jenkins was down for several minutes before being helped off the field. He was then carted to the locker room, but Jenkins said the use of the cart was a precaution.

"I really don't think I need it," Jenkins said of the MRI. "I walked over [to the locker] and I'm back walking good. It's a little swelling. We bumped knees. The first thing you expect [is something serious], you're just laying there. You don't want it to be the worst. I'm good, I can bend it and I have all my motion."

Cowboys owner Jerry Jones said the initial reports on Jenkins were good.

"It examined well," Jones said. "Now that doesn't mean anything until we get him in there [Monday]."

Tight end Witten suffered a concussion when the back of his head slammed into the turf after a 23-yard reception. Witten was taken down by two defenders and fell backward, and the back of his helmet slammed into the turf. Witten, who declined comment after the game, wanted to return, but the Cowboys medical staff refused to give him his helmet.

Witten missed the last 8:40 of regulation.

"[Witten] got banged up to where we had to hold him out," coach Wade Phillips said after the game.

Witten's status for Week 3 is up in the air.

Rookie wide receiver Dez Bryant limped off the field with a leg injury after he was flipped by Mike Hamlin, who was trying to block Brian Iwuh on a punt return. Bryant was upset as he limped to the sidelines and rode a stationary bike for less than a minute.

Bryant did return to the game.
