*Washington Redskins wide receiver Terrelle Pryor said via Instagram that he was called the N-word by a Kansas City Chiefs fan following Monday’s game, prompting him to curse out and flip off the person as he left the field.

The postgame exchange was caught on video and posted on TMZ, though mostly what is heard is someone shouting “f— you.” Pryor returned the shouts using similar language and raised his middle finger at the fan.

Pryor then started toward the person, raising his helmet, only to be restrained by Redskins strength and conditioning coach Chad Englehart. Pryor then continued to the locker room.

The NFL is reviewing all aspects of the incident, a league spokesman said Thursday, including what took place in the stands, according to ESPN.

Via Instagram Stories, Pryor wrote that he was called this “several times to the point where an NFL employee had to step to me and stand by me the whole game from second quarter on is the exact reason why guys are kneeling during the anthem.”

Pryor, who has stood during the anthem, said that after hearing someone call him the N-word and then having fans shout obscenities, “me flicking the person off is more deserving.”

“I do apologize to my teammates and the organization,” Pryor wrote. “But at some point you keep calling us The N word .. we going to start acting up. #straightlikethat.”
