Wesley suffered the injury during the second quarter against Minnesota on Sunday when he bumped knees with Timberwolves forward Jaden McDaniels.
Wesley was the 25th overall pick of the June draft after playing one season at Notre Dame, where he led the Irish in scoring (14.4 PPG). He was making just his second NBA appearance against the Timberwolves after contributing 10 points and four assists in 15 minutes against Chicago on Friday.
Wesley got a chance to join the rotation when the Spurs abruptly waived Joshua Primo last week after Primo allegedly exposing himself to women. Wesley’s injury could force San Antonio to make a move to shore up its backcourt depth.
