He sustained the injury during practice Wednesday, sources said.

California plays its tournament opener Friday against Hawaii.

Wallace is a unique point guard at 6-foot-6, and averaged 15.3 points, 5.3 rebounds and 4.4 assists in 28 regular-season games this season. Wallace broke a bone in his right hand in January and missed nearly one month.

Wallace is ranked No. 17 among seniors in the 2016 NBA draft, according to Jonathan Givony of DraftExpress.com and The Vertical.

Wallace has served as a leader on a Cal team featuring freshman standouts Jaylen Brown and Ivan Rabb. Cal has a 23-10 record and is the No. 4 seed in the South Region.
