North Carolina Tar Heels men's basketball coach Roy Williams briefly collapsed and was escorted to the locker room late in the first half of North Carolina's game at Clemson on Saturday.
Per ESPN's Myron Metcalf: Clemson head coach Brad Brownell yelled, "Hold up!" when he saw Williams on one knee on the opposing bench.
North Carolina announced the 68-year-old Williams experienced a bout of vertigo, an issue he has dealt with in the past. A similar situation occurred with Williams in 2016.
Williams waved to fans as he was escorted off the court.

He has coached the Tar Heels to three national championships, including the 2017 title at the Final Four in Glendale.
