According to the television broadcast, O'Brien was upset that the Texans only had 10 players on the field to start the half. He was restrained by outside linebacker Brian Peters, who was inactive for the game, and an assistant coach.
After the game, O'Brien initially denied that any argument occurred.
"I don't know what you guys are talking about," O'Brien said. "No idea."
When he was told there was video of the incident, O'Brien replied, “No, I don't think so. I don't remember that one bit."
When he was asked if there was an imposter out there on the sideline, O'Brien brushed off the incident.
"There's conversations that happen on the sideline," O'Brien said. “That's just kind of the nature of the game."
