Bennett, who had a meniscectomy on the knee at St. Mary's Hospital in Athens, was one of three Bulldogs who suffered right knee injuries in Saturday's 34-31 overtime win at Tennessee. However, he is the only one who will compete again this season.
Fellow receiver Justin Scott-Wesley also underwent surgery Tuesday to repair both menisci in his right knee. He will undergo ACL reconstruction at a later date, but Georgia director of sports medicine Ron Courson said Scott-Wesley should be able to return to practice without limitations by the start of 2014 fall practice.
Tailback Keith Marshall also suffered a torn ACL against Tennessee and will undergo reconstructive surgery "within the next three weeks," according to Georgia.
Running back Todd Gurley, who is still nursing a left ankle sprain, was held out of practice Tuesday and is doubtful to play this week.
Gurley also sat out against Tennessee, but coach Mark Richt left the door open for Gurley to play this week by saying, "We'll see how he runs just straight ahead."
"Is he going to play this game?" Richt said. "He could. We're not counting him out, but we have to prepare as if he won't play."
Richt said starting safety Tray Matthews is doubtful for Saturday's Missouri game, as well. Matthews did not play against Tennessee and has been out since tweaking his hamstring in last Tuesday's practice.
"He could possibly come around, but he's not going to practice today," Richt said.
