Wallace played for the Pistons for six seasons, helping the team win two Eastern Conference championships and a NBA title in 2004. The team hired Maurice Cheeks as their head coach last month to replace Lawrence Frank.
Wallace spent last season with the New York Knicks after coming out of retirement, but his season ended early because of a stress fracture in his foot.
More from the Detroit News:
Since leaving Detroit he’s dabbled in semi-retirement and also come out to play for the Celtics and Knicks, spending this season in New York before a stress fracture ended his season.
He doesn’t have to file retirement papers with the league because he was on a one-year deal with the Knicks, thus he isn’t on an existing contract. He’ll mainly work with the Pistons’ young bigs -- Greg Monroe, Andre Drummond and second-round pick Tony Mitchell.
