Jeff Driskel sidelined by ankle injury

GAINESVILLE, Fla. -- Florida quarterback Jeff Driskel's sprained right ankle will keep him from playing in Saturday's game against Jacksonville State, and possibly the regular-season finale against Florida State as well.

"We're just working through this week," Gators coach Will Muschamp said on the weekly SEC coaches' teleconference. "Whenever you deal with an ankle it's a day-to-day process. It's a situation that continues to improve. How much it'll improve into next week, I have no idea at this time.

"We feel like he'll be available, but who knows?"

Sophomore Jacoby Brissett will make his second start of the season Saturday. He completed 6 of 8 passes for 64 yards and one touchdown after Driskel was hurt late in the third quarter of Saturday's game against Louisiana-Lafayette. Brissett has thrown only 13 passes this season.

"Got a lot of confidence in Jacoby," Muschamp said. "It's his opportunity and I'm looking forward to seeing him play."

Jacksonville State's defense is among the worst in the 121-team Football Championship Subdivision. The Gamecocks rank 100th nationally in scoring defense (33.4 points per game), 86th in rush defense (186.2 yards per game), 110th in pass defense (260.7 ypg) and 108th in total defense (446.9 ypg).

Muschamp said on Monday that he was hopeful Driskel could practice on Wednesday, but his ankle has not improved enough for that to happen. The 6-foot-4, 237-pound sophomore has started the last nine games at quarterback since he and Brissett both started the season opener against Bowling Green (Driskel lined up at receiver). He has completed 64.8 percent of his passes for 1,324 yards and 10 touchdowns with three interceptions. He also is the Gators' second-leading rusher with 424 yards and four TDs on 97 carries.

Driskel was injured when he was tackled by Louisiana-Lafayette defensive tackle Jalen Fields late in the third quarter of the Gators' 27-20 victory. The 6-4, 229-pound Brissett replaced him and eventually led the Gators on a game-tying scoring drive which included a 39-yard pass to tight end Jordan Reed and a 3-yard touchdown pass to wide receiver Quinton Dunbar.

Brissett played in eight games last season and completed 18 of 39 passes for 206 yards with two touchdowns and four interceptions. He started against LSU and Auburn and played the entire second half of the Florida State game because of injuries to starter John Brantley.

Florida also will be without starting safety De'Ante Saunders (knee), kick returner Andre Debose (knee) and linebacker Neiron Ball (ankle) against Jacksonville State.
