Fireworks, axes, and pizza: 5 of the NFL's most bizarre off-field injuries

New York Giants defensive end Jason Pierre-Paul and Tampa Bay Buccaneers cornerback C.J. Wilson both lost fingers in separate fireworks-related incidents over the July 4th weekend.

As foolish as their actions were, Pierre-Paul and Wilson aren't alone. Here are five other bizarre NFL injuries that occurred off the field:

May 5, 2002: Brian Griese injured while running down steep driveway

Former Denver Broncos quarterback Brian Griese had his fair share of drinking-related accidents, but this one takes the cake.

Griese was attending a barbecue at teammate Terrell Davis's house, and ended up knocking himself unconscious while running down the driveway toward his car. Griese admitted to enjoying "a few" beers beforehand, but placed the blame solely on the steep driveway.

The tumble left Griese with a black eye, seven stitches, and a chipped tooth.

Oct. 9, 2003: Chris Hanson injured while swinging ax in locker room

In his first season as head coach of the Jacksonville Jaguars, Jack Del Rio decided it would be a good idea to place a tree stump and an ax in the middle of the locker room to symbolize his mantra: "Keep choppin' wood."

Every now and then, Jaguars players would take a swing with the ax, leaving wood chips scattered across the floor. Unfortunately for the team's punter, Chris Hanson, he swung and missed, taking a slice out of his non-kicking leg instead. The injury required surgery, and kept him out of the final 11 games.

March 22, 2008: Brandon Marshall injured while slipping on empty McDonald's bag

Brandon Marshall is a reminder to us all to put our garbage where it belongs.

During his third season with the Broncos, the wide receiver was horsing around with family members when he slipped on a McDonald's bag and went crashing into his entertainment center.

Marshall severed a vein, nerve, artery, and five muscle tendons in his right forearm and was sidelined for several months. He later revealed that he played the entire 2008 season with little feeling in his right hand.

Sept. 24, 2013: Nate Burleson injured while attempting to save falling pizza

In the early hours of Sept. 24, 2013, then-Detroit Lions wide receiver Nate Burleson was driving westbound on Interstate 696 when he attempted to save a pizza box that was falling off one of the seats in his car. He ended up striking a median and broke both bones in his forearm.

Burleson was sidelined for two months as a result of the accident, but he did get free pizza for a year and a pretty sweet touchdown celebration out of it. A win for pizza-lovers everywhere.

Sept. 24, 2014: Joseph Fauria injured while attempting to stop peeing puppy

Exactly one year after Burleson's pizza-related incident, Lions tight end Joseph Fauria suffered a sprained left ankle while trying to prevent his three-month-old puppy, Lil' Rufio, from peeing inside his house.

As Fauria would later recount, he was chasing Lil' Rufio down stairs and took a misstep, putting all his weight on his left foot. Fauria missed six games and was placed on IR late in the season after aggravating the injury. But really, though, how could you be mad at a face like this?
