O.J. Mayo of the Milwaukee Bucks was ejected from the team's game against the New Orleans Pelicans for punching Greg Stiemsma on Friday.
The incident occurred late in the first quarter of the game, according to Pro Basketball Talk's Brett Polakoff. Stiemsma appeared to rattle Mayo with a screen, and the Milwaukee guard retaliated with a blow to the head.
The Bucks were already without forward Ersan Ilyasova for Friday's game after he was suspended for attacking Reggie Evans of the Sacramento Kings earlier in the week.
