The Detroit Pistons announced that forward Jon Leuer underwent surgery on Wednesday to repair a meniscus injury in his right knee. His status for training camp has yet to be determined.
Leuer underwent season-ending ankle surgery earlier this year after appearing in just eight contests last season.
The 29-year-old is entering the third season of a four-year, $41-million contract with the Pistons.
He was productive during his first year in Motown, averaging 10.2 points and 5.4 boards in 75 games.
