The NFL hates fun. Baltimore Ravens linebacker Paul Kruger has been forced to remove the fan-favorite back flap he’s been sporting this season.

According to the Baltimore Sun’s Aaron Wilson, Kruger was fined $5,000 for a uniform violation. Kruger says he plans to appeal the fine, claiming the league never warned him about it.

It is strange that the league waited until week 14 to send Kruger the bill.

Kruger tweeted that the flap always had his back and retweeted a few fans supporting his trademark style.
