Well, it didn't take Watt long to respond. On Wednesday, the Texans star defensive end took to Twitter to fire back.
A lion doesn't concern himself with the opinions of a sheep. Time to attack the day.— JJ Watt (@JJWatt) July 8, 2015
The social media war between Watt and Mettenberger began last October when Watt pretended to take a selfie after sacking Mettenberger. Watt said he did it to poke fun at Mettenberger for taking selfies before the Texans-Titans game. It was Mettenberger's first career start.
"JJ had to say it's a bit high school-ish that I take selfies and I think he still rags me on Instagram every time he posts a selfie," said Mettenberger in the interview posted Tuesday. "At the same time, if that's high school-ish, he got a letterman jacket made, a Texans letterman jacket. That's pretty high schoolish to me, don't you think?"
The full interview can be seen below.
