James Wiseman will undergo surgery to repair a meniscus injury in his right knee on Thursday.

Steve Kerr said that a timetable couldn't be determined until afterwards. 

Kerr added that the team spoke to several medical experts before deciding on surgery. 

"He's a young guy -- this isn't supposed to happen so early in someone's career. So it's a tough time for sure. So fingers are crossed, and we'll see how everything goes [Thursday]," said Kerr.
