University of Alabama junior center Ryan Kelly returned to practice in a limited capacity on Wednesday, but isn’t expected to play this week.

Nick Saban described him as “doubtful” for Saturday’s home game against Texas A&M (3:30 p.m. ET, CBS).

“It’ll probably be another week before we really get him back,” he said Wednesday evening.

The coach also announced that emergency running back Ronnie Clark tore his Achillies, “Just taking a step backwards” on Tuesday, and is done for the season. The true freshman switched from the secondary last week after Alabama was down to three healthy halfbacks and senior fullback Jalston Fowler due to injuries.

However, the backfield has been bolstered this week by the return of redshirt freshman Tyren Jones, after having surgery to repair a torn tendon in his finger. Saban said he might available against the Aggies.

Kelly sustained a sprained knee against Ole Miss and has not practiced since the 23-17 loss on Oct. 4. He was expected to be out 2-3 weeks. After facing the Aggies, Alabama visits Tennessee next week before having its final bye week of the season.

It turns out he wasn’t the only injured player on the offensive line as Saban disclosed that senior left guard Arie Kouandjio was limited by an ankle injury last week.

“Arie didn’t practice maybe more than 15 reps in practice last week because of his ankle,” he said. “We have a new center. We played a different guy at right guard. So there were a lot of changes. Maybe with healthier players and more continuity we’ll continue to make progress, and I also think that we have to do a better job of executing all the way around.”

Redshirt freshman Bradley Bozeman has played in Kelly’s spot and made his first career start at Arkansas last Saturday.

In other Alabama injury news, sophomore offensive lineman Grant Hill returned to practice after being out two weeks due to an illness.

Junior wide receiver Amari Cooper (knee) and senior tight end Brian Vogler (ankle) have been practicing with the team being limited earlier in the week.
