Detroit Pistons center Isaiah Stewart was arrested for assault Wednesday for punching Phoenix Suns center Drew Eubanks at the arena hours before the teams played. Phoenix police said Stewart was issued a citation and released. Eubanks said before the game that the altercation happened as he was coming into the arena. He said an argument started and they were chest-to-chest before Stewart threw the punch. Security intervened and Eubanks said he was fine for the game, though police say he sustained a minor injury.
