On Saturday, Green Bay Packers running back AJ Dillon went viral after absolutely demolishing the Kenosha Kingfish mascot at a celebrity softball game. It was a brutal hit that sent the mascot’s head flying off that sent Twitter buzzing. Now, we have the inside story of how it all happened.

According to The Athletic, Trey Meier, the name of the man wearing the mascot suit, is just a college kid who runs cross country at the University of Wisconsin-Milwaukee. “He makes $12.50 an hour as an intern for the Kingfish, a baseball team in the Northwoods League.” On Saturday, he was put in a position to square off against the Packers star AJ Dillon.

During a phone call with The Athletic, Meier claims he didn’t know he’d be going up against Dillon. “The emcee who was running the game actually told me, ‘Oh, yeah, you’re gonna be doing the Oklahoma drill with AJ Dillon.” Hilariously, Trey Meier didn’t think much of it. He probably believed the Packers’ star running back wasn’t going to go as hard as he did.

“Right when I found out about me doing the Oklahoma drill, I actually texted my dad. I was like, ‘Guess who’s about to do the Oklahoma drill against AJ Dillon?’ He texted me back and was like, ‘What?! You got this.’ And yeah, I did not have it at all.”

Even though Trey Meier went viral, he maintained his professionalism as a mascot, per The Athletic. “The one thing that I was worried about when I got hit, I was like, ‘I’ve got to get my head back on.'” After getting crushed by the Packers star, Meier was able to get back to his feet and get the head back on as soon as possible.

“I kind of played it off like the head was supposed to come off, like I was kind of trying to pump up the crowd a little bit, but that was not supposed to happen, and I got the head on as quickly as possible.”
