Key injuries for several teams

Posted by ESPN.com's Chris Low

Several SEC teams were hit with key injuries over the weekend, including Georgia losing another starter for the season.

Defensive end Rod Battle tore his ACL in the 41-37 win over South Carolina and will miss the rest of the season. The Bulldogs lost offensive tackle Trinton Sturdivant for the season in the first game.

LSU running back Richard Murphy injured his right knee against Vanderbilt and will undergo an MRI this week to determine the extent of the injury. There's a fear that he might have torn ligaments.

Auburn tight end Tommy Trott hurt his left knee late in the first half against Mississippi State, and his status for this weekend is unclear.

Alabama redshirt freshman defensive end Damion Square has a knee injury that coach Nick Saban said would likely require surgery. Star receiver Julio Jones bruised his kneecap on the opening drive, and running back Roy Upchurch sprained an ankle. Neither player returned to the game.

South Carolina defensive tackle Nathan Pepper could miss two to three weeks after spraining his ankle against Georgia. The Gamecocks were already without middle linebacker Rodney Paulk, who tore his ACL in the opener, and defensive tackle Ladi Ajiboye, who's suspended for the first three games.

If Pepper doesn't play this week against Florida Atlantic, either Melvin Ingram or Kenny Davis would replace him.

Vanderbilt was really hit hard by injuries in its 23-9 loss to LSU. Starting offensive tackle James Williams broke his ankle and will likely miss the rest of the season. Starting safety Ryan Hamilton could also be out indefinitely after suffering an injury to his upper right chest. His arm was in a sling in the second half, and the Commodores will know more about his status after he undergoes further evaluation by doctors.

Other Vanderbilt players injured in the game and missing time were linebacker Patrick Benoist (shoulder) and nickel back Jamie Graham (ankle).

The top candidates to replace Williams at right tackle are redshirt freshman Caleb Welchans, junior Reilly Lauer and sophomore Kyle Fischer. Lauer and Fischer had been working primarily at guard this season.
