It's official: John Brantley is out for LSU. GatorZone's Scott Carter was first to tweet it, and the Palm Beach Post's Jason Lieser has the full quote from Florida coach Will Muschamp.

"John Brantley will be out this week. I will update you each Monday on his status."

That certainly sounds like an injury that can be evaluated on a week-to-week basis, which tends toward confirmation of the reports that Brantley's injury is a high ankle sprain. Muschamp called the injury a "lower leg injury."

Muschamp also told media at his Monday press conference that Jeff Driskel will be the Gators' starting quarterback against LSU. But Muschamp did not rule out the possibility of playing multiple quarterbacks.

Driskel has played sparingly in relief of Brantley in 2011, and the touted true freshman has been largely ineffective. Though he broke the longest run against Alabama this season in the second half of Saturday night's 38-10 loss to the Crimson Tide, Driskel has completed just seven of 16 passes for 73 yards this season, and has thrown two interceptions.

Florida plays LSU at Tiger Stadium this Saturday. The game will be broadcast at 3:30 p.m. on CBS.
