Terrelle Pryor was captured in the tunnel of Arrowhead Stadium on Monday night giving the finger to a fan.

Pryor looked pretty pissed off and while some of that may have been due to Washington losing frustratingly to the Chiefs, it seemed like an especially emotional reaction to heckling.

TMZ Spots posted a video of the incident.

Now Pryor has gone to social media to explain the situation. The former Ohio State Buckeye wrote that he was called the n-word throughout the game to the point that an NFL employee had to intervene.

Pryor wrote,

“Being called a n***** several times to the point where an NFL employee had to step to me and stand by me the whole game from 2nd quarter on is the exact reason why guys are kneeling during anthem… As I walked in tunnel hearing some one call me a n***** and say F you to me … flicking the person off is more deserving. I do apologize to my teammates and the organization. But at some point you keep calling us the N word .. we going to start acting up. #straightlikethat”

The NFL is now looking into the incident, according to Adam Schefter.

This is an ugly situation, especially considering the current racial landscape of the NFL, where fans have booed teams for taking knees or protesting during the national anthem.

NFL fans are predominately white, the players are predominately black.

This has led to tension in recent weeks as players protesting racial injustice in America has been met with grotesque counter-reaction from NFL fans who find some sort of personal offense in the demonstrations.

As Pryor pointed out in his post, this sort of treatment by fans is precisely why players are kneeling in the first place.

The social and political environment of America right now is a powder keg ready to blow and this is translating into sports arenas and the field. This is some ugly shit.
