GAINESVILLE, Fla. — Florida quarterback Jeff Driskel is transferring to Louisiana Tech for his final year of college eligibility.

Driskel, who will be a fifth-year senior, will be eligible to play immediately under the NCAA’s graduate transfer rule.

“I look forward to the upcoming chapter of my life,” Driskel said in a statement released by Florida. “I have nothing but good things to say about the University of Florida and the football program there. ... Although things did not play out on the field as I would have liked, I have no regrets on the choice I made to attend UF.”

Driskel completed 59 percent of his passes for 3,411 yards at Florida, with 23 touchdowns and 20 interceptions. He also ran for 644 yards and nine scores.

Also, new Florida coach Jim McElwain added a number of assistants.

Having already hired Doug Nussmeier as offensive coordinator and Geoff Collins as defensive coordinator, McElwain filled several more staff positions Monday.

The biggest name in the group was former Miami coach Randy Shannon, who was hired as associate head coach, co-defensive coordinator and linebackers coach.

McElwain also hired Terrell Williams as defensive line coach and Kirk Callahan as defensive backs coach.

On offense, McElwain retained offensive line coach Mike Summers, hired Greg Nord as tight ends and special teams coach, and hired Tim Skipper as running backs coach.

Mike Kent will serve as director of strength and conditioning.
