Oakland Raiders running back Marshawn Lynch sat during the national anthem Saturday evening prior to a National Football League pre-season game against the Arizona Cardinals.

It is unclear if Lynch was protesting a particular cause, but head coach Jack Del Rio was quick to say that he was not.

“I talked to Marshawn, I wanted to make sure we’re on the same page,” Del Rio told reporters following the game. “He said this is something I’ve done for eleven years, it’s not a form of anything other than me being myself.”

“I said just so you understand how I feel, I very strongly believe in standing for the national anthem, but I’m gonna respect you as a man,” Del Rio said he told Lynch. “You do your thing, and we’ll do ours.”
