Acker, who flew to Athens to see the city and living conditions before signing the deal with Olympiakos, knows his role with the Pistons this season would be limited.
The Pistons gave newly signed guard Flip Murray jersey No. 6, which Acker wore last year.
The Pistons made a qualifying offer to Acker that would pay him $664,000 for 2006-07, which Acker most likely would spend mostly in the development league.
The Pistons would still retain rights to Acker should he sign with Olympiakos. Via The Detroit News
