Orlando Magic head coach Stan Van Gundy is accusing Dallas Mavericks center Brendan Haywood of punching center Dwight Howard in the back during Dallas’ 100-98 win Friday night."It's really ridiculous and I want to get it on film and send it in (to the league office)," Van Gundy told OrlandoMagic.com. "Haywood just punched him literally with a closed fist right in the back. So (Howard) got through the game because he was loose, but then it really tightened up. "They are going to work on him and hopefully he'll be OK. But (Howard) didn't do anything today."Howard did not practice Saturday and was scheduled to see a back specialist. The Magic do expect him to play against the Denver Nuggets Sunday.Van Gundy did not specify when the punch occurred. Haywood declined to comment when asked by reporters.
