Following UNC’s 97-73 blowout win over rival NC State on Wednesday night, head coach Roy Williams announced that sophomore guard Kenny Williams will miss the rest of the season with a right knee injury.

The younger Williams watched the game from the sidelines while wearing a suit, after suffering the injury in practice on Tuesday.

“He hurt his knee,” Roy Williams told reporters after the game. “It’s a crazy thing. It’s not an ACL or anything like that, it’s four to six weeks.

“But four to six weeks at this point in the year, it’s basically the end of the season.”

It’s a major blow for the Tar Heels, who have dealt with injuries to both Theo Pinson and Isaiah Hicks in recent weeks, as they approach the stretch run.

Pinson started in Williams’ place against NC State, and likely will continue to do so for the rest of the year.

Although Pinson’s versatility and playmaking will be a plus for the team, it will be tough to replace Williams’ defensive presence–especially given the way UNC has struggled on that end of the floor this season.

“It’s hard thinking about how we’re gonna get better, when I’ve said all year long that Kenny’s our best perimeter defender,” Roy Williams said Wednesday after the game. “He really is.”
