Martin suffered the injury following a collision with another player during a workout. He will have surgery on Thursday by team physicians Dr. Fred Azar and Dr. Drew Murphy at the Campbell Clinic in Memphis; no timetable was given for his return.
Martin sat out of summer league with a stress fracture in his foot that he first announced at his introductory press conference in late June. Martin said he went through rehab on the foot leading up to the draft and would continue doing so throughout the summer.
Martin, 21, was the Grizzlies’ first-round draft pick, No. 25 overall, out of LSU. Over two seasons with the Tigers, Martin averaged 13.7 points and 6.9 rebounds over 30.7 minutes per game.
