Pistons big man Isaiah Stewart has been suspended three games without pay for initiating an altercation with Suns big man Drew Eubanks before last week’s game in Phoenix, the NBA announced.

Stewart punched and pushed Eubanks during the incident, per the league’s statement. His suspension is expected to begin on Thursday vs. Indiana, as Detroit’s forward/center was set to be active tonight for the first time in several weeks after dealing with an ankle sprain.

Eubanks said he was sucker punched in the face by Stewart in the hallway of the Footprint Center shortly after arriving at the arena, though he wasn’t injured and was able to suit up for the Suns’ victory last Wednesday. Stewart was arrested on a misdemeanor assault charge and issued a citation before being released.

Stewart, 22, is averaging 11.0 PPG and 6.8 RPG on .470/.374/.746 shooting in 35 games (30.6 MPG) this season for the Pistons, who hold the worst record in the league at 8-46
