In what is his latest injury setback, Philadelphia 76ers forward Paul George underwent successful arthroscopic surgery on his left knee Monday after sustaining an injury in a recent workout, the team announced.

The Sixers said George is beginning a rehab program and will be re-evaluated prior to the start of training camp.

George's first year in Philadelphia did not go according to plan. His season ended in March after receiving injections in his left adductor muscle and left knee. George had hyperextended that knee during a preseason game and wound up playing only 41 games overall.

In the first season of a four-year, $212 million contract, George averaged 16.2 points per game, his lowest average since returning late in the 2014-15 season from a compound leg fracture.

The 76ers finished the season 24-58, 13 games out of a play-in spot in the Eastern Conference. George, a nine-time All-Star, turned 35 in May.
