The Detroit Pistons have decided to fire Lawrence Frank, sources tell RealGM's Jarrod Rudolph.

An official announcement came on Thursday afternoon.

The Pistons were 29-53 under Frank this season, his second with the Pistons. Detroit improved by just four wins over last season's 66-game mark.

Frank had reportedly wanted to be fired unless the Pistons picked up their option for his contract for the 14-15 season.
