Preseason No. 1 Georgia has already suffered a loss.
The Bulldogs announced on Tuesday that left tackle Trinton Sturdivant needs reconstructive surgery on his injured left knee and will be out for the season.
On Monday, Sturdivant went down with a knee injury in the team's first scrimmage of the season in Athens, Ga.
"It swelled up pretty good, and we're taking the pictures so we'll see," coach Mark Richt said Monday night, according to the school. "It's just sad to see a guy get hurt."
The sophomore started all 13 games at left tackle left season and earned freshman All-America and freshman All-SEC honors.
Sophomore Josh Davis replaced Sturdivant for the remainder of practice.
