DALLAS (105.3 THE FAN) — Dallas Cowboys owner Jerry Jones says he’s “pretty positive” that running back DeMarco Murray and right guard Zack Martin will be available to play on Sunday against Indianapolis.

He’s less positive about right tackle Doug Free.

“Murray and Martin I’m pretty positive about having the ability to play them,” said Jones with the G-Bag Nation on 105.3 The Fan. “I’m a little skeptical that we’ll have Free. Let’s see what the next few days bring.”

Free and Martin both suffered ankle injuries in last week’s win in Philadelphia.

Jones also suggested that Free could be available to play on a part-time basis, which would warrant an active roster spot for Sunday.

However, he believes the Cowboys have one of the best swing tackles in football in Jermey Parnell — though he’s sometimes inconsistent.

“I don’t think anybody has a better swing backup tackle in the NFL.”
