TUSCALOOSA _ University of Alabama senior inside linebacker Trey DePreist returned to practice Tuesday after being out two days with an apparent knee injury.

DePriest was in his usual spot for individual drills during the Crimson Tide’s observation period for reporters, and wore a protective brace on his left knee.

It was Alabama’s first workout in full pads, and also the hottest day of training camp so far. The temperature was 97 degrees, with a heat index of 99, under a hot sun. The only break the players got was the humidity being a mild 32 percent.

DePriest, who is expected to call the plays in the defensive huddle this season, has played in 40 games for Alabama, with 26 starts. This past season he had 65 tackles, 7½ for a loss, two sacks, two fumble recoveries and one interception.

He sustained the injury Saturday, and spent Sunday and Monday conditioning on the sideline.

No players wore a black, no-contact jersey during individual drills, although that could have changed after reporters departed. Also of note, junior-college transfer Dominick Jackson was working with the second-unit offensive line at right guard, and Dakota Ball continues to go through drills at both tight end and defensive line.

Alabama is scheduled to hold its first two-a-day on Wednesday.
