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.
