Sophomore JuJu Smith-Schuster, USC’s leading receiver, is undergoing surgery today to repair a broken right hand, the school announced.

It’s unclear when Smith-Schuster will be able to return. Interim coach Clay Helton said in a university-produced video that the procedure could “speed up” Smith-Schuster’s recovery process. But it’s far from a sure thing.

“Obviously, everybody heals differently,” Helton said. “It’s been as soon as three days, or it could take longer. When he’s healthy and he feels like he can go back out there, he will.”

Smith-Schuster leads USC in receptions (52), receiving yards (956) and touchdowns (eight). He ranks first in the Pac-12 and seventh in the nation in receiving yards per game (119.5).

Smith-Schuster suffered the injury early in USC’s 27-21 victory at Cal on Saturday. He was in and out of the lineup after that, finishing with five catches for 55 yards.

USC plays host to Arizona at 7:30 p.m. this Saturday.
