Davis played well in Anderson's absence against Auburn last week as part of a line that didn't allow a sack and helped the Bulldogs rack up 136 rushing yards.
"I thought Josh had one of his best games," left tackle Clint Boling said. "He played hard, he played tough, finished blocks. I'm glad he was able to step in and play so well."
Davis started Georgia's opener at right tackle while Boling served a one-game suspension, but was relegated to the bench for most of the remainder of the season prior last week.
"I know Josh has been waiting a lot," Boling said. "People have gone down this year, and he's finally gotten his chance, and I think he's just stepping in and playing really well, embracing it and taking it upon himself to play well."
Richt said Anderson is recovering from a foot injury and could be healthy enough to play by game time but likely will not have had enough reps during practice to be ready for action.
"He's a guy, as most young guys are, he needs reps to make sure he's ready to play good enough," Richt said of Anderson, a redshirt freshman. "He might be ready by the game, but I doubt he'll have the reps to feel comfortable."
