David Singleton crumpled to the floor, held his ankle, and then wrapped his arm around the team trainer tending to him. It was clear he was in pain. Coach Mick Cronin met him out on the court, then told TNT sideline reporter Dana Jacobson after the game Singleton was scared about a serious injury in the moment.

When Singleton went down with an apparent ankle injury, UCLA fans held their breath, having already lost star defender Jaylin Clark and watched standout freshman big man Adem Bona miss time with a shoulder injury.

Singleton says there’s nothing to worry about, though.

“I just rolled my ankle,” he said, per The LA Times’ Ben Bolch. “I’m fine.”

Singleton turned his ankle late in the Bruins’ 68-63 win over Northwestern. He’s the Bruins’ best 3-point shooter, connecting on 43% of his attempts so far this season. No one else in the rotation shoots the 3-ball above a 35% clip. If he’s unavailable for the Bruins’ Sweet 16 matchup or limited, it would be a significant blow.

Of course, that’s been said multiple times now and the Bruins keep winning.

Singleton was a key part of the latest victory. For most of the game, he struggled with his shot, missing each of his first four triples. But Singleton splashed a 3 on the break with 1:52 to play that put UCLA up by six points. The shot came immediately on the heels of a block from Bona — a five-point swing that was a turning point in the game.

UCLA will face either 3-seed Gonzaga or 6-seed TCU in the next round of the NCAA Tournament.
