North Carolina guard Cameron Johnson will be out of action for the time being after undergoing knee surgery on Wednesday.
Per North Carolina's athletic website, Johnson suffered a torn meniscus during practice on Nov. 13 and was having surgery to repair the injury at UNC Medical Center.
A timetable for Johnson's return will be established after he is out of surgery, per the school's athletic website.
"I'm extremely disappointed for Cameron," North Carolina head coach Roy Williams said in the release. "The young man has been working hard to blend in with our team after being such a productive college player the last two-plus seasons."
Johnson is in his first season as a member of the Tar Heels. The senior spent the previous three years at the University of Pittsburgh before moving to North Carolina in June as a graduate transfer, allowing him to play immediately.
The 21-year-old missed North Carolina's season opener against Northern Iowa on Nov. 10 due to a neck injury. He averaged 11.9 points and 4.5 rebounds per game at Pittsburgh during the 2016-17 season.
