The Clemson Tigers men's basketball team took on the Louisville Cardinals Friday evening with a spot in the ACC title game on the line, and the ending was full of controversy.

The ACC is using the secondary locker rooms at Spectrum Center for teams in the men’s basketball tournament. The lockers are split into Locker Rooms 1 and 2 (lower seed) and Locker Rooms 3 and 4 (higher seed), per signage at the arena.

Clemson’s late rally wasn’t enough to overcome Louisville, as the Tigers fell 76-73 in the ACC Tournament Semifinals on Friday night. Despite trailing by 15 points with just over three minutes remaining, Clemson fought back to give itself a chance in the final moments before ultimately coming up short at the Spectrum Center.

The 10th-ranked Clemson Tigers trailed No. 13 Louisville 33-28 at halftime of Friday night’s semifinal game at the ACC Tournament and were in need of some in-game adjustments. So it didn’t help when the Tigers found themselves locked out of their locker room at halftime.
