Trimble last played 36 total minutes in the victory over Kansas. He dropped 17 points with eight rebounds and dished three assists in the 87-74 romp at Chapel Hill.

Trimble didn't take long to react to Sunday's devastating news — by posting this Instagram story.

His head coach Hubert Davis released a school statement, shared via Inside Carolina on On3/Rivals.

“So sad for Seth,” Davis began. “He’s such a great kid and teammate and has worked so hard for his senior year. He loves being a Tar Heel, and we love him. The good news is he will be back at some point this year, and I know he will continue to be a great leader for us until he can get back in the lineup.”

Juniors Kyan Evans and Jaydon Young are among the experienced Heels left in the guard room. The former scored 12 against the Jayhawks.
