New Orleans Pelicans forward Quincy Pondexter’s recovery from Wednesday’s surgery will last longer than expected, multiple sources with information on the procedure told The Advocate on Thursday.

Rather than just having arthroscopic surgery on his left knee, Pondexter’s doctors also successfully repaired a cartilage injury, typically a more invasive surgery that requires a significantly longer recovery time. The Pelicans declined to release a timetable on his recovery.

Pondexter played in every Pelicans game following his trade from Memphis on Jan. 12, shooting 43 percent from 3-point range and stabilizing the wing position as the team snapped a four-year playoff drought to earn the No. 8 seed. He averaged nine points and 3.1 rebounds in 45 games with the Pelicans.

Team sources said they are confident he could be back during preseason training camp, but it’s still unclear how long he will be sidelined.

This is not Pondexter’s first significant injury. He had surgery for a tarsal navicular stress fracture in his right foot in December 2013; that caused him to miss nearly the entire 2013-14 season.

Pondexter is under contract with the Pelicans through 2017-18, with an average salary of $3.4 million.
