Marvin Williams missed the Hawks' game at Dallas on Saturday night and also will sit out at home against Toronto on Wednesday night. Shawne Williams will sit out when the Knicks host Detroit on Sunday.
Hawks coach Larry Drew accepted the length of Marvin Williams' suspension without protest.
"There was no real expectations on the length as far as I was concerned," Drew said. "I didn't even see the instant replay. I knew something would take place as far as a suspension. The league made a ruling on it and we just have to live with it."
Drew said Williams, who can't be in the arena for games while he's suspended, was back at the team hotel and in good spirits.
"I saw him at breakfast and he was in great shape," Drew said. "He's ready to move on. It's an unfortunate set of circumstances and you've got to put it behind you."
Marvin Williams has already missed 15 games this season with back and right knee injuries.
