The young center will seek a second opinion on the knee injury that has been slow to heal, the Los Angeles Times reported on Monday. Bynum will see Dr. Steven Gecha on Wednesday in Princeton, N.J.
Bynum, who averaged 13.1 points and 10.2 rebounds through 35 games, was injured Jan. 13, suffering a bone bruise and briefly dislocating his knee cap.
The 20-year-old has been taking part in one-on-one drills but has been experiencing swelling. He has yet to go through a full practice.
Bynum's contract is up at the end of the season and he was in line for a maximum deal after the Lakers passed up multiple offers for the big man in trade scenarios.
