DAVIE, Fla. -- Former Pro Bowl running back Arian Foster is expected to make his debut with the Miami Dolphins on Friday against the Dallas Cowboys, according to Dolphins head coach Adam Gase.

Foster, who is returning from an Achilles injury, missed last week's preseason opener against the New York Giants due to a coach's decision.

"Right now I'm pretty sure he's going to go," Gase said of Foster. "So unless I change my mind for some reason, I want to see him get in there with that first group and get him a feel for how they operate."

Foster began training camp on the physically unable to perform list but has practiced with Miami the past two weeks. He's looked mostly solid running and catching and is in a close competition for a starting job with second-year running back Jay Ajayi. Both running backs have shared time with the first team.

The Houston Texans cut Foster this offseason after he played just four games due to injury last season. He has 6,472 career rushing yards and 68 total touchdowns.
