North Carolina senior guard Joel Berry II will miss the first few weeks of the season with a broken hand, the school announced Monday.

It's unclear how Berry sustained the injury, but North Carolina said he will miss "approximately four weeks."

Berry was a cornerstone for UNC last year, averaging 14.7 points and 3.6 assists and helping the Tar Heels win the 2017 national championship.

He was voted the 2017 Final Four's Most Outstanding Player and scored a game-high 22 points against Gonzaga in the title game.
