Just how deep does the disdain for NFC East rivals run for New York Giants running back Rashad Jennings? Apparently deep enough for him to walk out on a chiropractic appointment after discovering the doctor was a Philadelphia Eagles fan.

I went to see a chiropractor. He said he was an Eagles fan. I got off the table and left before he said another word. Too close. #Gmen — Rashad Jennings (@RashadJennings) July 19, 2016

Jennings, who is deeply devoted to his physical well-being, is likely kidding about his walk-out, but that doesn’t make it any less amusing. Of course, on the other hand, if he did truly walk out without saying a single word, it will likely become the stuff of legend among Big Blue fans and forever cast Jennings as an idol.

The Giants are rarely, if ever, shy about expressing their hatred for NFC East opponents; namely the Philadelphia Eagles and Dallas Cowboys. And for whatever reason, it seems like the team’s running backs are often the most vocal.

“I hate the Cowboys with a bloody passion,” now-retired running back Brandon Jacobs said in 2009.

Since his retirement, Jacobs has maintained his hatred of the Cowboys, often poking fun at them via Twitter. He’s also had his fair share to say about the Eagles.

In the case of Jennings, you can all but guarantee this will be brought back up come Week 9 when the Giants host the Eagles at MetLife Stadium. Neither the Eagles nor their fans find humor in this sort of thing and forever seem to be seeking whiteboard material.

And for whatever it may be worth, Jennings rushed for 233 yards and a touchdown against the Eagles last season. Chiropractor or no chiropractor, he’ll be looking to duplicate those numbers in 2016.
