DeMarco Murray (hand) questionable

IRVING, Texas -- Dallas Cowboys running back DeMarco Murray went through his second straight practice in which he was limited and is listed as questionable on the injury report.

Owner and general manager Jerry Jones said on 105.3 The Fan in Dallas on Friday morning that he was "pretty positive" Murray, who had surgery Monday to repair a broken left hand, would play Sunday against the Indianapolis Colts. Murray, the NFL's leading rusher, actually held the ball at times in his left hand during the brief portion of practice open to the media.

On Thursday, Murray said the final decision to play would be his, and coach Jason Garrett agreed to an extent.

"He knows how he feels more than anybody else," Garrett said. "It's our job as coaches and the medical staff to evaluate him and see if he's functional. If we see things that don't add up to what he's saying about how he's feeling, we'll certainly have that communication. But he's the one that knows about himself more than anybody, and we trust his feedback. He's a veteran player. He knows what it takes to play in a game."

Murray and the Cowboys won't know until Sunday if he can withstand the pain of getting hit over and over on carries. Murray carries the ball predominantly in his right hand, but he does deliver stiff arms and break his fall at times with his left hand. He would also have to pass protect.

He is wearing a hard plastic shell on the top of his glove for added protection. It is possible he could take pain medicine before kickoff to get through the game.

"You try your best to make your best educated guess," Garrett said.

Right guard Zack Martin has not practiced this week, but he was able to do some on-field rehab work Friday with his sprained right ankle and was optimistic he would play. He is listed as questionable, while right tackle Doug Free is listed as doubtful after he missed his third straight day with an ankle injury.

Quarterback Tony Romo (back), linebacker Rolando McClain (knee), safety Jeff Heath (thumb), cornerback Tyler Patmon (knee/ankle) and defensive end George Selvie (thumb) are probable. Backup quarterback Brandon Weeden missed practice for personal reasons.

Defensive tackle Josh Brent will miss his second straight game with a calf injury. Linebacker Dekoda Watson (hamstring) was also ruled out.
