The Pac-12 did not issue any suspensions Friday over the scuffle between Arizona and Oregon State players at McKale Center on Thursday, league spokesman Dave Hirsch said.
Two players were ejected and two others received technical fouls on the play but Hirsch said league officials found no punches thrown and determined no further penalty was necessary after reviewing the incident.
"The officials acted appropriately on the court and there are no suspensions," Hirsch said.
Arizona's Kyryl Natyazhko and OSU's Joe Burton were ejected for leaving the bench, but that penalty does not carry automatic suspensions. Players who are ejected for fighting face suspensions but neither was ruled to be fighting.
"I think Kyryl got caught up in the emotion but it wasn't like he had his hands on anyone," UA coach Sean Miller said. "He just moved out from the bench and sometimes you don't know what that means when you're doing it."
In addition, UA's Kyle Fogg and OSU's Jared Cunningham left the floor but only because they both fouled out during the play and its aftermath.
Fogg appeared to initiate the confrontation when he gestured at Cunningham after picking up a foul from Cunningham on his basket and, possibly because of momentum he had when he was hugged by teammate Nick Johnson, he bumped into Cunningham.
Miller declined to say specifically whether he believed Johnson inadvertently pushed Fogg into Cunningham but said, "I don't think the intent of anyone on our team was to do anything more than be emotional at a very key moment in the game."
After Fogg bumped Cunningham, the OSU guard pushed Fogg back and players from both teams heated up as Cunningham spoke to an official. After Natyazhko and Burton left their benches to join the melee, they were not assessed technicals but were ejected.
"Today, you can't leave the bench and you can't throw a punch," Miller said. "Not that that was ever right, but to me in our world today, now more than ever, that's not something that's going to be tolerated by anybody and it's certainly not going to be tolerated by the University of Arizona or our program. But nobody threw a punch."
Bill McCabe, the Pac-12's coordinator of officials, said similar scuffles are common in college basketball.
"This happens," McCabe said. "In about two of 20 games, there's somebody pushing somebody and getting a technical foul. I see it twice a weekend."
