The injury occurred Tuesday in practice, just days before the team's showdown with South Carolina. The matchup will be significant in the rankings and also for SEC positioning given that both teams are ranked in the top six programs nationally.
Bennett, a redshirt sophomore, is the team's leading receiver with 24 catches for 345 yards and four touchdowns. He burst onto the scene after finishing 2011 with just 320 receiving yards.
The injury puts extra pressure on Malcolm Mitchell. After starting the season as a defender, Mitchell is returning to offense, where he will now likely assume a large role. As a freshman last season, Mitchell had 665 receiving yards and four touchdowns.
The Bulldogs play the South Carolina Gamecocks at 7 p.m. on Saturday.
