Utah Jazz forward Paul Millsap will undergo surgery to repair a torn ulnar collateral ligament in his left thumb this Thursday, Jazz general manager Kevin O’Connor announced today.

Millsap injured the thumb in the Game Six loss to the Los Angeles Lakers on May 16. Following x-rays, Jazz physician Dr. Lyle Mason preliminarily diagnosed the thumb injury as a torn ulnar ligament.

A second opinion by Dr. Steven Huish today confirmed that Millsap suffered a torn ulnar collateral ligament in his left thumb, and Dr. Huish will perform surgery to repair the ligament on Thursday in Salt Lake City.

A report on the surgery and an estimated timeline for Millsap’s recovery will be provided on Friday.

Originally selected by the Jazz in the second round (47th overall) of the 2006 NBA Draft, Millsap has appeared in all 164 regular season games and all 29 playoff games in his first two seasons. He averaged 8.1 points and 5.6 rebounds in 20.8 minutes per game this season.
