Rivers ejected as Hawks give Celtics the boot again

Then chaos broke out.

Boston’s Glen Davis, dunked on by Josh Smith on the previous possession, found himself chasing down Marvin Williams on another fast break. This time, though, Davis wrapped up Williams in a bear hug that earned the big forward a flagrant foul.

“I was surprised,’’ Davis said. “I’m a big guy. I don’t feel like I did it intentionally. Really, when I was coming down, I was trying to hold him from falling. The refs made a decision. I can’t get mad and upset at them.’’

Said Williams, “I’ve been in that position, too, outweighing a guy by 40 pounds. I know Big Baby. He’s not the type of guy to try to hurt me. I haven’t seen what it looked like. He got me pretty good. Was it that bad? I don’t know. That’s what happens sometimes.’’

Within seconds, though, Celtics coach Doc Rivers went from confused to livid.

“I was so shocked at what they were calling,’’ Rivers said. “I thought they were talking about was it a breakaway [foul] or not. The last thing I had in my mind, I didn’t even think flagrant.’’

Rivers flew off the handle, and the technicals were flying close behind.

Rivers was assessed two, and was ejected by referee Bennett Salvatore.

“It was kind of fast,’’ said Celtics center Kendrick Perkins, who was on the receiving end of a flagrant foul by Zaza Pachulia earlier in the game. “It wasn’t within like 5 seconds. It was like ‘tech,’ then you’re thrown out the game.’’

Celtics assistant coach Armond Hill, lingering on the court, was hit with a third technical from referee Marc Davis.

“He didn’t say anything,’’ said Brian Scalabrine, who had 9 points and five rebounds in his first start of the season. “He just said, ‘Baby fouled him on the way up.’ And he got it.’’

“Honestly, from what I heard from the players, they were just searching the bench,’’ Rivers said. “Whoever was saying anything was going to get a tech and Armond was the guilty party. Armond felt awful. You know Armond. It’s tough for Armond to get a tech.’’
