Parker responded with his fourth 3-pointer of the game with 57 seconds left to seal the win for the Bulldogs.

The Bulldogs were coming off a hard-fought loss at No. 16 Kentucky on Saturday. They got off to a strong start against Ole Miss but were unable to distance themselves from the Rebels until the second half.
Ogbeide hit a jumper and a free throw that put the Bulldogs up 23-15 with eight minutes left in the first half. Ole Miss answered with an 11-3 run, capped by a layup from Tyree that tied the score 26-26 late in the half.
Georgia's Jordan Harris hit a 3-pointer, and Maten followed with seven consecutive points to give the Bulldogs a 39-31 lead at intermission.
Ole Miss was up and down during nonconference play. The Rebels suffered suspect losses to Illinois State and Middle Tennessee but opened SEC play with a win over South Carolina. They couldn't follow it up with a win over the Bulldogs on Wednesday, though.
The Rebels will return home and look to bounce back when Mississippi State visits on Saturday.
Georgia hosts Alabama on Saturday.
