Chicago Bears quarterback Jay Cutler, who missed a game after sustaining a concussion, said he was not sure whether he would be able to play against the Minnesota Vikings on Sunday.

The quarterback said he felt well physically but had not yet been cleared by doctors to play.

"I met with the doctors on Monday morning and have to wait and see how things go during the week," Cutler said.

The quarterback had to sit out the Bears' game on Monday night against the San Francisco 49ers, a game that the Niners won 23-7.

Cutler said he did not know whether he was kept off the field because he failed his medical tests.

"Before undergoing the tests, I met with the trainers and they were all leaning toward us not playing," Cutler said, referring to defensive end Shea McClellin, who also sat out the game after sustaining a concussion against the Houston Texans on Nov. 11.

Cutler sustained the concussion on a hit by Texans linebacker Tim Dobbins, who was later fined $30,000 by the NFL for the shot on the quarterback.

Cutler, who has sustained other concussions, said he did not plan to change the way he plays. EFE
