The Pistons announced the injury Tuesday. It was discovered following a CT scan Monday.
Meeks signed a $19.5 million, three-year deal with the Pistons this offseason. He was diagnosed with back spasms last week and had additional testing done because of continuing discomfort.
Meeks started 70 games last season, averaged a career-high 15.7 points and shot 40 percent from 3-point range for the Los Angeles Lakers. He's the second Detroit guard to go down with an injury recently. Kentavious Caldwell-Pope is dealing with a left knee strain, although the team said an MRI showed no structural damage.
