J.J. Watt dons Penn State gear to pay off Big Ten title bet

J.J. Watt is more than willing to pay up on a bet, he just doesn't have to be happy about it.

The Houston Texans star made a wager with teammate Devon Still on the outcome of the Big Ten title game. If Wisconsin, where Watt played two seasons, won the game, Still would have to wear Badgers gear, while if Still's Nittany Lions were victorious, Watt would be decked out in Penn State merchandise.

After Penn State emerged with a 38-31 victory, Watt had to pay off the bet on Friday.

Watt, whose younger brother T.J. Watt is a linebacker on the Badgers, retweeted the picture and was gracious enough to offer the Nittany Lions good luck in their Rose Bowl matchup with USC.
