ATHENS — Nick Chubb has shown “some improvement,” but not enough to practice fully yet this week, according to Georgia head coach Kirby Smart.

Chubb sprained his ankle in the first half of the Ole Miss game, and didn’t return. Smart was non-committal on what he’ll be able to do the rest of the week.

“I don’t know that. Based on today I would say I don’t know. Because I don’t know,” Smart said. “He’s getting better though.”

Chubb has been rehabbing during the early portion of practice, then has come out after the media viewing period.

“Right now he’s in a boot, trying to keep the pressure off it,” Smart said. “He’s able to do some light running stuff.”

The star tailback’s yardage and carries have decreased each game: From 222 rushing yards on 32 carries against North Carolina, to season-lows of 57 yards on 12 carries at Ole Miss.

The latter was mainly because Chubb didn’t return to the game after his first-half injury. But he’s gone from averaging 6.9 yards per carry in the opener to 3.9 per carry over the next three games.
