Tyrone Wallace has suffered a fractured bone in his right hand, sustaining the injury in practice on Wednesday.
Wallace will undergo further evaluations on his non-shooting hand before Cal's NCAA tournament opener against Hawaii on Friday, sources said, but his status for the tournament has been placed in jeopardy.
Wallace is ranked No. 17 among seniors in the 2016 NBA draft, according to Jonathan Givony of DraftExpress.com and The Vertical.
Wallace is averaging 15.3 points, 5.3 rebounds and 4.4 assists this season for Cal. Wallace broke a bone in his right hand in January and missed nearly one month.
