On Monday, Dabo Swinney 'cut loose' freshman cornerback Mackensie Alexander, in hopes that he'd to able to hit the field full-speed against South Carolina State.
But during Tuesday's practice, Alexander re-aggravated his groin injury, and Clemson announced that he will not play on Saturday against the Bulldogs.
Although Swinney offered no long-term prognosis on Alexander, it appears likely that the five-star recruit - the highest-rated member of Clemson's 2013 recruiting class - will be forced to redshirt this season.
Alexander first suffered the injury on the second day of practice, August 3, and has been sidelined since.
Out of high school, Alexander was rated as the nation's No. 4 player overall by ESPN.
