In the one-on-one interview, Mettenberger said he was set up by a couple of his friends and that his selfie was leaked before the Texans-Titans game.
During the game, right after Watt sacked Mettenberger, the Texans star defensive end stood over the quarterback and pretended to do the selfie pose.
"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. "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?"
