Jason Pierre-Paul is giving us a lesson in fireworks safety.
The Buccaneers defensive end posted photos on Instagram of his mangled hand from three years ago from when he blew part of it off handling fireworks.
Warning: The image below is very graphic.
"One of the greatest American traditions in celebrating 4th of July is with fireworks. Unfortunately, tomorrow someone will be injured playing with fireworks," Pierre-Paul wrote on Instagram. "We are celebrating the birthday of our great nation. I'm glad to still be alive to show you the outcome of what happened to me.
"Please don't feel sorry for me, trust me your boy fine even with missing fingers lol. Be safe out there otherwise, this can be you."
Pierre-Paul has returned to the NFL after the injury — he's currently prepping for his first season with the Buccaneers. But he missed most of 2015 recovering from the accident.
Last season, he recorded 8.5 sacks and 68 tackles with the Giants.
