The Memphis Grizzlies today announced that guard Jordan Adams will undergo cartilage transplant surgery on his right knee today, Wednesday, June 15.

In August 2015, Adams underwent a lateral meniscectomy on his right knee after sustaining a partially torn meniscus during an off-season workout.

Sidelined for most of the summer and limited in training camp, Adams returned to play for a short period before suffering an unrelated injury to the articular cartilage in his right knee. Adams subsequently underwent a debridement surgery on January 12, 2016.

Following that surgery, Adams participated in a lengthy rehab program, extending through the second half of the 2015-16 season, in an effort to resume basketball activities.

On March 18, Adams told Grizzlies.com, “I have been working hard throughout my rehab process to get back and join my teammates on the court as soon as possible. I am trying to ramp up my cardio workouts as of late and hoping to get back to practice soon.” On March 25, it was announced Adams increased his daily activity, beginning on-court workouts.

However, Adams was ultimately unable to return to contact play without pain in his right knee and after his latest evaluation by the team’s medical staff, Adams and the medical staff determined that a cartilage transplant is in his best interests. He will be out indefinitely. Updates on Adams will be provided when available.

“This is obviously difficult news for Jordan and our organization,” said Grizzlies General Manager Chris Wallace. “Jordan has been on a tough road for the better part of a year. We wish him a full and speedy recovery and hope that this procedure will help him return to the hardwood.”

The surgery will be performed by Dr. Riley Williams at the Hospital for Special Surgery in New York.
