LANDOVER, Md. -- Chicago Bears quarterback Jay Cutler left Sunday's 45-41 loss to the Washington Redskins with a groin injury and will undergo an MRI on Monday to determine the extent of damage to the area.
Cutler suffered the injury with 10:09 remaining in the second quarter while being slammed to the ground on a sack by Chris Baker.
Bears coach Marc Trestman said he didn't "have any sense at all" about the severity of Cutler's injury.
"We'll know more in the next couple of days," Trestman said. "It's a groin. It's not a knee, it's not an ankle, it's not a hip. We'll see where we're at. I'm just going to wait to see what the doctors say."
In the meantime, the Bears (4-3) are set to bring in Jordan Palmer as a potential backup to Josh McCown, a source told ESPN. The Bears signed Palmer and Trent Edwards at the end of the preseason after former No. 3 quarterback Matt Blanchard fractured a knuckle on his throwing hand.
Trestman on Monday said the addition of Palmer was "certainly an option."
"We're just going to sit back here today and evaluate the game and coach our guys up to the best of our availability, and we'll see where Jay is at and what the prognosis is for the next couple weeks and work from there, but Jordan certainly is an option," Trestman said in an interview with WBBM-AM in Chicago.
Before the Bears opened the postgame locker room for media access Sunday, Cutler was seen on the back of a cart being driven through the bowels of FedExField toward one of the exits.
Cutler appeared to suffer the injury as Baker swung him to the ground, causing the quarterback's lower body to slam down on top of the defensive end's knee. Cutler eventually limped off the field under his own power, and the team's medical staff immediately walked him into the locker room.
McCown filled in and completed 14 of 20 passes for 204 yards, including a 7-yard touchdown pass to Martellus Bennett in the fourth quarter. McCown finished the game with a passer rating of 119.6.
"When you're close to somebody and they get hurt, your heart just kinds of sinks," McCown said. "I was bummed, said a prayer, grabbed my helmet and got some throws in to get ready to play."
Before the injury, Cutler was 3-of-8 passing for 28 yards and had an interception returned 29 yards for a touchdown by Redskins linebacker Brian Orakpo.
The Bears hope to know the extent of Cutler's injury by Monday or Tuesday.
"You never want to see your starting quarterback go down," running back Matt Forte said. "When your starting quarterback goes down and you are used to him playing, it kind of does something mentally to you. We didn't want to see anything like that out there."
Cutler hasn't missed time since Nov. 11 of last season, when he sustained a concussion against the Houston Texans that forced him out the next week against the San Francisco 49ers. In 2011, Cutler missed the club's final six games because of a broken thumb, and the Bears lost five of those games.
Chicago is optimistic that the upcoming week off might help Cutler through any potential recovery process. After a team meeting Monday morning at Halas Hall, the Bears won't practice again until Oct. 28.
"Jay leads our team. He's our quarterback," Trestman said. "We want him out there. We want him playing. I'm just hopeful that it's not too serious, that this one comes at the right time [because of the upcoming bye]."
