Tashard Choice has calf strain

SAN ANTONIO -- Cowboys running back Tashard Choice missed the morning walkthrough with a calf strain. He's listed as day-to-day.

Choice suffered the injury in Thursday's afternoon practice.

The Cowboys' third-round draft pick, DeMarco Murray, made an appearance at Friday's walkthrough, but didn't participate due to a hamstring injury. Murray will be placed on the Non-Football Injury report because he suffered the injury prior to training camp. His return is uncertain.

With Murray and Choice out, it left the Cowboys with Felix Jones, Phillip Tanner and Lonyae Miller at the running back spot for the walkthrough. Chris Gronkowski and Shaun Chapas were the fullbacks.
