Chandler Parsons had 'minor hybrid' procedure on right knee, sources say

DALLAS -- The procedure that Dallas Mavericks forward Chandler Parsons had on his right knee on May 1 was a "minor hybrid" microfracture operation, according to sources.

Parsons, who averaged 15.7 points per game in his first campaign with the Mavs last season, has not been fully cleared for the beginning of training camp but remains optimistic that he will be able to play in the Mavs' Oct. 28 season opener.

The Mavs and Parsons have been vague about the details of the operation, which was announced simply as an "arthroscopic surgery to address a cartilage injury in his right knee."

Sources told ESPN.com that the operation, which was performed by team physician T.O. Souryal, included a bone marrow transplant from Parsons' right hip to help regenerate the cartilage damage from late last season that caused him to miss all but one game of the playoffs.

The location of the cartilage damage was in the "best possible spot," a source said, because it is in a non-weight-bearing area of the knee. That was the primary reason that a traditional microfracture surgery, which would require a longer recovery period, was not necessary.

Shooting guard Wesley Matthews, the Mavs' $70 million free-agent addition who is recovering from a torn left Achilles tendon suffered in March, has also not been fully cleared for the beginning of camp but remains determined to play in Dallas' season opener.
