Team spokesman Craig Pinkerton says Lofton wore a walking boot on his foot as a precaution while the Vols rested on Monday and was expected to practice on Tuesday.
Coach Bruce Pearl told The Knoxville News Sentinel that Lofton "tweaked" his ankle in the first half of Tennessee's 76-71 overtime win against Butler in the NCAA tournament.
Lofton leads Tennessee with 15.5 points per game.
