Gators coach Muschamp says Brissett or Driskel will start against No. 24 Tigers

GAINESVILLE, Fla. - John Brantley is out, Jacoby Brissett is penciled in and Jeff Driskel is still trying to return from a sprained ankle.

All that really means is the Florida Gators still don't know which quarterback will start Saturday night at No. 24 Auburn.

It won't be Brantley, who missed last week's 41-11 loss at top-ranked LSU because of a badly sprained right ankle and was ruled out again Monday.

Brissett started in his place and completed 8-of-14 passes for 94 yards, with a touchdown and two interceptions.

Coach Will Muschamp said Brissett will open practice this week as the starter, but added fellow freshman Driskel could get back in the mix.

"They both are going to practise through the week," Muschamp said. "Based on the injury report I got this morning, Jeff should practise today.

"How limited he will be, I do not know that. But those guys will work with Jacoby as being the starter at this point and we'll work through the week and progress to see who practises the best."

Driskel earned the backup job during fall practice and was expected to start at LSU. But he missed the game because of a sprained ankle, the severity of which Muschamp declined to reveal during media sessions last weeks.

"I wasn't trying to gain anything," Muschamp said. "I wasn't sure until Wednesday night that Jeff was not going to play in the game."

Driskel played in four of Florida's first five games, completing 44 per cent of his passes for 73 yards. He has no touchdowns, two interceptions and a fumble.

Muschamp defended his decision to keep his quarterback situation quiet.

"I do think you gain from the standpoint if Jeff Driskel's the quarterback, it's a guy they've seen on tape," Muschamp said.

If Driskel is healthy enough to practise, Muschamp said he and Brissett would split repetitions in workouts before settling on a starter.

Either way, Muschamp expects the offence to change.

The Gators looked like they used last year's playbook against LSU, with running back Chris Rainey and fullback Trey Burton taking snaps in the wildcat formation. It failed miserably.

The Gators (4-2, 2-2 Southeastern Conference) managed 213 yards, one of the program's worst offensive performances in more than two decades.

"Certainly, we've got to do something else offensively," Muschamp said. "If you continue to do the same things, you'll get the same results. So we need to change."
