Georgia’s heralded freshman defensive lineman Travon Walker is out of action, but is not expected to be out long.

Walker, 6-foot-5, 290-pound defensive end from Thomaston did not play against South Carolina on Saturday and has not been participating in the Bulldogs’ practices this week. On Tuesday night, coach Kirby Smart revealed the 5-star recruiting prospect underwent surgery on his wrist.

“He had something bothering him, and they ended up finding out what it was,” Smart. “He’s expected back real soon, like next week.”

Walker has been playing regularly, but not extensively for the Bulldogs. He had five tackles and half a sack in five games as a reserve on the defensive line. He also is a starter on Georgia’s kickoff team.

Smart also provided an update on quarterback D’Wan Mathis. The freshman from Bellville, Mich., has practiced but been unable to have contact all season after undergoing emergency brain surgery early this summer. Mathis is expected to receive a medical redshirt this season.

“He’s getting to do more,” Smart said. “He’s getting to do some scout-team things and do more activity. But he’s still not cleared to play and take live reps soon. And we’ll hope that’ll be soon.”

Smart said leading receiver Lawrence Cager (shoulder) likely won’t play Saturday against Kentucky.
