Tennessee redshirt freshman quarterback Nathan Peterman will make his first career start on Saturday at Florida, the Vols announced just 90 minutes before kickoff.
Tennessee's offense had sputtered in the first three games, and the Vols (2-1) will play the Gators (1-1), which have one of the most formidable defenses in the country (TV: CBS, 3:30 p.m.)
A native of Fruit Cove, Fla., Peterman redshirted in 2012. He has played in all three games this year in a relief role, completing 6 of 12 passes for 40 yards.
Peterman unseated junior starter Justin Worley who had completed 35 of 57 passes for 357 yards with five touchdowns and one interception in three games.
Worley won the starting job after a lengthy competition that spanned spring and summer.
The Vols also have two true freshman quarterbacks, Riley Ferguson and Josh Dobbs. Dobbs was not on the travel roster for the Florida game, so Ferguson will likely be the third option if the Vols choose to go deeper on their bench.
