The incident occurred with 7:16 remaining in the fourth period of the Heat's 109-103 loss to the Bulls on Wednesday at United Center.
"I don't know what he was trying to do," Deng told the Chicago Tribune. "I have to see the play again. I don't want to say anything bad. I went up and I didn't really see him make an attempt for the ball."
"I don't know if it's something he sets out before the game to do or not," Hinrich told the Tribune. "It was a hard foul, obviously."
The Bulls thought Posey should have received a longer penalty,
especially since he was suspended a game in April for a flagrant
foul against Kirk Hinrich during the first round of the playoffs.
"I thought it was light," Chicago coach Scott Skiles said.
Posey served the suspension Friday in New Jersey when the Heat faced the Nets.
