Irvin, who said he was overcome with emotion after seeing teammate Michael Bennett get hit, took to Twitter to explain his actions.
I want to apologize to all of the younger kids for my actions last night. I was trying to protect my brother and it got out of hand.— Bruce Irvin (@BIrvin_WVU11) February 2, 2015
It's easy to say u would have done different but in the heat of the moment I just reacted when I seen my brother get punched.— Bruce Irvin (@BIrvin_WVU11) February 2, 2015
Still not an excuse and I'm truly sorry to all the 12's and my Wvu family for my actions.— Bruce Irvin (@BIrvin_WVU11) February 2, 2015
With the New England Patriots having secured another title with an interception just moments before to seal what was a 28-24 victory, Patriots quarterback Tom Brady was attempting to simply take a knee with 20 seconds remaining at his 5-yard line.
"I was protecting a teammate, emotions flew," Irvin said Sunday night. "I saw somebody hit Mike Bennett, so I went and backed up my brother. I went about it wrong. Emotions were flying high, and I apologize.
"But if it happened again, I would go protect my teammate. That's just how it is."
Wendell and Irvin were shoving back and forth in the back of the end zone. With the officials focused on the pile of players in the middle of the field, Irvin and Patriots tight end Michael Hoomanawanui were locked up.
Irvin threw Hoomanawanui to the ground as players were separated.
"I don't know, they just started coming at us. We were just trying to take a knee," Gronkowski said. "Just happens, it's football, just emotions going.
"It's football, things happen. It's all good. I mean, it's all good. They played ball, they're a hardworking team and we just came out and did what we did to get the win."
