The NFL might want to warn its players about pizza. A year after an errant pie caused Nate Burleson to break his arm in a car accident, Washington cornerback DeAngelo Hall tore his Achilles tendon making a pizza in his kitchen.

Hall re-tore his Achilles' tendon in his kitchen getting some pizza, Gruden said. — Mike Jones (@MikeJonesWaPo) October 31, 2014

Not kidding: DeAngelo Hall was making a pizza in his kitchen and slipped. THAT is how he re-tore his repaired Achilles' tendon. I can't even — Brian McNally (@bmcnally14) October 31, 2014

Going to repeat that for effect ... MAKING A PIZZA IN HIS KITCHEN.

The list of things NFL players should avoid now includes:

1. Discount Double Check sack celebrations

2. pizza

3. Strip clubs with Pacman Jones
