Muschamp said Driskel will "probably" start but both quarterbacks will play regardless of who takes the field first.
Driskel, a redshirt junior, started the team's first four games of the season but was pulled in favor of Harris in Florida's Oct. 4 game against Tennessee with the Gators still scoreless in the fourth quarter. Harris then engineered two scoring drives to lead the team to a 10-9 win.
The following Monday, Florida suspended Harris indefinitely after an allegation of sexual assault was made against the freshman by a fellow student relating to an incident that occurred early Sunday morning. He was not arrested or charged at the time, but university police conducted an investigation.
Harris's lawyer adamantly denied the accusation and said he didn't expect Harris to be prosecuted. On Friday, the woman who made the allegation withdrew her complaint and Harris was reinstated to the team, though he was held out of the Gators' game against LSU on Saturday.
In Florida's 30-27 loss to the Tigers, Driskel went 14-for-25 for 184 yards, one touchdown and two interceptions. His second interception led to LSU's game-winning field goal with three seconds remaining. Driskel has completed just 49.6 percent of his passes in SEC play and has thrown seven interceptions in Florida's last three games, a stretch in which the Gators have gone 1-2.
Driskel was informed of the team's new two-quarterback system on Monday.
"Treon and I are both going to work hard this week," he said. "We're going to work for each other. If it will help the team, I'm all for it."
Harris went 2-for-4 for 17 yards and ran the ball four times for 24 yards against the Volunteers. In his only other game action this season, Harris threw touchdown passes of 70 yards and 78 yards against Eastern Michigan in Florida's season opener in his only two pass attempts.
Florida is 3-2 overall this season and 2-2 in the SEC. Missouri is 4-2 and 1-1 in the SEC.
