Georgia will be without starting inside linebacker Alec Ogletree for the next four to six weeks after he broke a bone in his right foot Saturday night in the Bulldogs' 35-21 loss to Boise State.
Ogletree will undergo surgery Monday.
"That's four to six weeks usually, so that's a big blow," Georgia coach Mark Richt said Sunday.
The 6-foot-3, 236-pound Ogletree was injured late in the first quarter Saturday.
He was one of the players Georgia defensive coordinator Todd Grantham was counting on to make a big difference after making the move from safety. Ogletree was one of the Bulldogs' best defenders in the preseason.
Georgia isn't particularly deep at linebacker, and senior walk-on Jeremy Sulek played most of the snaps at Ogletree's "Mo" position after Ogletree left the game Saturday. True freshman Amarlo Herrera also played some at that position, while Richt said junior Mike Gilliard could also be in that equation against South Carolina on Saturday.
Richt said Sulek has a better understanding of the Bulldogs' defense right now and is probably ahead of the other two. He finished with seven tackles against Boise State.
Georgia's inside linebackers will be especially important in Week 2 with South Carolina and Marcus Lattimore coming to town. Lattimore pounded his way to 182 yards on 37 carries last season in the Gamecocks' 17-6 win over the Bulldogs and rushed for 112 yards and three touchdowns in South Carolina's season-opening 56-37 win over East Carolina on Saturday.
