Celtics' Irving to have surgery on left knee
The Celtics say All-Star point guard Kyrie Irving is set to have surgery Saturday to alleviate pain in his left knee.
Irving has been out since March 11, missing the last four games. There is no timetable for his return, but the team says his status will be updated following the "minimally invasive" procedure.
He is one of several key sidelined players for Boston.
