Raptors guard Williams undergoes knee surgery

TORONTO -- Raptors point guard Alvin Williams underwent
arthroscopic surgery on his right knee this week, the team
announced Wednesday.

Dr. James Andrews in Birmingham, Ala., removed bone spurs and cleaned up scar tissue from Williams' knee on Tuesday.

Williams, who had microfracture surgery last year on the same knee, is out indefinitely. He missed all of last season and has
played in just one game this year.
