Cowboys fan stabbed in fight with Redskins fan at FedEx Field (VIDEO)

A video posted on Facebook shows Washington and Dallas fans fighting after their Monday night NFC East divisional game at FedEx Field, and in it a Cowboys fan was reportedly stabbed.

The footage shows a man in a Jason Witten Cowboys jersey sitting on the ground being attended to by someone in a Redskins jacket.

Mike Vaughn, who posted the video, said in the clip that the fan was stabbed and that there was a knife on the ground. Authorities confirmed to Fox 5 DC that a knife was recovered in the concourse and they are investigating. Two arrests were made.

"Wowwwww. This place is a war zone right now. Fights breaking out everywhere. One dude got stabbed," Vaughn wrote on his Facebook page.

WARNING: Graphic language in video.

"We are aware of an altercation that took place at FedEx Field following Monday's game," the Redskins said in a statement issued to Fox 5 DC.

"We thank members of the Prince George's County Police Department who responded promptly to break up the altercation and arrested both men involved. Neither sustained injuries that required hospitalization. We will continue to gather more information on the matter and ensure the safety of all fans at FedEx Field."

Redskins president: Team won't change name for new stadium: Report

Washington Redskins President Bruce Allen made it crystal clear Monday the team would not reconsider whether to change the team’s nickname if it became a political barrier to building a new stadium in the nation’s capital or elsewhere.

The club currently plays at FedEx Field — which opened in Landover, Maryland, in 1997 — and has started exploring sites for a new facility, even though its lease there runs until 2026.

At a news conference before the Redskins' last practice of training camp Monday, Allen said the team has spoken with representatives of Washington, Virginia and Maryland about a spot for a stadium.

“We’ve had great conversations with all the areas, and the design is something that we’ve started on,” Allen said, “but really it is preliminary right now.”

Interior Secretary Sally Jewell told Washington Mayor Muriel Bowser in April that the National Park Service — which owns the land where the team’s former home, RFK Stadium, sits in the city — wouldn’t grant a new lease because of objections to the team’s name. Owner Dan Snyder has said he will never change the nickname.

When asked Monday about the possibility of revisiting that policy if the name is a political barrier to a new location for the stadium, Allen quickly gave a one-word answer: “No.”

RFK Stadium sits on land owned by the National Park Service that is leased to the city. The lease expires in 22 years. The city would need an extension to build a new stadium there. Altering the lease would require an act of Congress, and the city could seek Congressional support for a change in the lease without the Park Service’s blessing.
