Jarrett Guarantano came off the bench to help Tennessee to a 41-21 win against South Carolina on Saturday evening, but it came at a cost for the embattled quarterback.

Vols coach Jeremy Pruitt told the Vol Network after the win that Guarantano suffered a broken bone in his left (non-throwing) wrist and is set to undergo surgery on it on Sunday morning, but the second-year coach added he thought Guarantano would be available for next week's game against UAB (7 p.m., ESPNU).

Guarantano spoke to the media after the game sporting a cast on his left wrist.

The former starter, benched in favor of freshman Brian Maurer at the start of October, came off the bench in relief of J.T. Shrout against South Carolina and was 11-of-19 passing for 229 yards and two touchdowns, both to Jauan Jennings.

“I could have played a lot better,” Guarantano said. “I think that there’s some times where I could have did some things, but the team won and that’s really all I’m worried about. But there’s definitely a lot of room to improve.”

Guarantano suffered the injury on his second touchdown pass to Jennings, a 19-yard score, when he took a big hit after letting the ball go.

Maurer missed Saturday's game and the Vols rotated a trio of players at quarterback in Guarantano, Shrout and wide receiver Jennings, who technically started the game.

Guarantano addressed the play on which he suffered in his injury after the game.

“They were playing Cover Zero, and they brought, I think, six or seven (defenders),” he said. “I knew that I was going to have to get the ball out on like a little half roll-out. I knew I was going to take one, but I didn’t know where the ball was going to go. I knew I was going to go in somewhat that direction after I saw (Jennings) cut, and good thing it ended like that.”

Pruitt said after Tennessee's loss to Georgia that Guarantano would help the Vols win some games down the stretch of the season, and Guarantano has proven his head coach right twice this month alone. Guarantano came off the bench after Maurer suffered a concussion and was 6-of-7 passing for 106 yards and a touchdown against Mississippi State. He made some costly mistakes, most notably a goal-line fumble that turned into an Alabama touchdown, last week, but put it behind him and delivered in another win against South Carolina.

“I was just very happy with these guys,” Guarantano said. “I love seeing the smiles on their faces when they win, and that’s really the most important thing to me right now.”
