NFL Media Insider Ian Rapoport spoke to a source who was optimistic about the running back playing Sunday.
"He's tough, he has a high pain threshold and he feels good," the source said. "(I) wouldn't be surprised if he plays."
Murray leads the NFL with 405 offensive touches this season, while carrying it 351 times for 1,687 yards and 11 rushing touchdowns. In the last two weeks the 26-year-old runner has 30-plus carries in each contest.
"He hasn't done much with the ball in his left hand," coach Jason Garrett told reporters Friday. "He's trying to work his way back -- he just had surgery a couple days ago. So, I think, again, his mind is right, he has a long away to go, we'll take it day by day, and we'll see how he is come game time."
"Whatever happens I'll be ready if they need me," Randle said. "I'm 100 percent confident I can get the job done if the team needs me to step in."
If Murray is able to gut it out with a cast on the left hand, there will be questions about how much of a load he can carry, especially when called to pass block or be involved in the air game.
"Murray and Martin I'm pretty positive about having the ability to play them," Jerry Jones told KRLD-FM on Friday.
