Winona High School graduate Alec Brown suffered a dislocated shoulder in an NBA Summer League game in Las Vegas Friday against Dallas.
Yahoo Sports reports Brown left the game with his left arm in a sling after he dove for a ball.
The injury is still being evaluated.
Brown was drafted by the Phoenix Suns in the second round in June and is hoping to make the Suns team. Second round draftees are not guarenteed an NBA contract.
