The Dallas Cowboys are optimistic that DeMarco Murray will be able to play on Sunday against the Indianapolis Colts.

Murray underwent surgery on his broken on Monday and can wear a cast that allows him to play.

"He's as strong-willed and determined an individual as I've ever been around,'' Jason Garrett said. "And if anybody has a chance to come back, he does."

The Cowboys will publicly note Murray as a "game-time decision'' for the Colts, the team will actually get a feel for his availability during the practice week.

Joseph Randle and Lance Dunbar will get carries for the Cowboys if Murray is unavailable.
