Georgia won its season opener over Georgia Southern, 45–21. Georgia led 38–0 in the 3rd quarter before replacing many of its starting players. Knowshon Moreno scored 3 touchdowns on eight rushing attempts. Georgia lost its #1 ranking after the game and would never regain it, losing it after this game in part to USC's 52–7 win over Virginia and the perception that Georgia's defense was questionable for allowing three touchdowns to a lesser opponent.
A. J. Green recorded his first career touchdown on a 3-yard pass from back-up quarterback, Joe Cox.
Georgia coasted to a second straight victory to start the season, beating Central Michigan, 56–17. Knowshon Moreno had 3 touchdowns and 168 yards on 18 carries.

Matthew Stafford completed 15 of 25 passes for 146 yards, but his biggest play came on a 30-yard 3rd quarter run to the South Carolina 4, setting up a Knowshon Moreno touchdown run on the next play. Moreno had 79 yards on 20 carries. A. J. Green led the Georgia receivers with 3 catches for 61 yards.

ESPN's College Gameday broadcast their show live from Athens before the Alabama game. The visit was the show's first broadcast from Athens since the Tennessee game in 1998. A. J. Green led all Georgia receivers with 6 catches for 88 yards and a touchdown. This game was notable in that it was only the third ever "blackout" game where the team donned black jerseys and the majority of the fans wore black. However, unlike earlier two contests which were both big Georgia wins, the Crimson Tide dominated early in the game and built an insurmountable 31-0 halftime lead from which Georgia was unable to recover. After the disappointment of this game, the bulldogs would never have another blackout game until 2016 where they faced against Louisiana-Lafayette.
Georgia ended a 2-game losing streak to Tennessee with a 26–14 win in Athens. Stafford had 310 yards passing in his first career 300-yard passing game.
