Per Marc Spears:
An NBA official said the situation with Celtics guard Rajon Rondo's hard foul on Chicago's Brad Miller in Game 5 yesterday in Boston stands as is. There was some concern that Rondo could get a Flagrant Foul or more due to the hard foul.
The league made the right call in terms of not over-reacting and suspending Rondo. I'll admit that I'm surprised that they didn't upgrade the foul to a flagrant, and maybe assess a fine. However, under no circumstances should there have been a suspension.
Update: Here's the explanation from the league:
"We felt Rondo was making a basketball play and going for the ball after a blown defensive assignment by the Celtic team," Jackson said.
"In terms of the criteria that we use to evaluate a flagrant foul penalty one, generally we like to consider whether or not there was a windup, an appropriate level of impact and a follow-through. And with this foul, we didn't see a windup, nor did he follow through. So for that reason we're not going to upgrade this foul to a flagrant foul penalty one."
