DENVER — After the terror attacks in Paris, the National Football League moved Saturday to assure fans, employees and players that this week’s games will be safe to attend.

Two of the coordinated attacks in Paris occurred outside of a stadium where France was playing Germany in a soccer match.

Some 17 million fans attend NFL games every year.

The NFL said it was “closely monitoring events” and was working with the FBI and the Department of Homeland Security.

At the time of the statement, there were no perceived threats against stadiums.

There are 12 NFL games scheduled for Sunday.

“[S]ecurity at our games is robust,” the NFL said. “There will be an increased security and law enforcement presence both inside and outside stadiums in the parking lots of our stadiums this weekend.”

The NFL explained that it screens all attendees using metal detectors and uses several layers of security to protect against bomb threats.

The league also offered tips to game-goers: Don’t bring bags to the stadium unless they’re made of a clear material.

The full statement from the NFL is below.  

The safety of our fans, stadium personnel, and teams at all NFL games is our priority, and security at our games is robust. Our procedures have been certified and designated by the Department of Homeland Security since 2008 as effective anti-terrorism technology. All NFL clubs use mandatory metal detector screening and multiple layers of perimeter security external to the stadium to safeguard fans and the stadium from explosive threats.

Following the events in Paris on Friday, we are closely monitoring events and have been in communication with the Department of Homeland Security and the FBI, which have informed us that there are no known threats against NFL stadiums.

In addition to our standard procedures described above, there will be an increased security and law enforcement presence both inside and outside stadiums in the parking lots of our stadiums this weekend. We have been in contact with clubs hosting games to reinforce our standard procedures and the league’s best practices.

We strongly recommend that fans do not bring bags with them to the stadium. If it is essential to bring a bag, it must be in compliance with the clear bag policy which requires that it be made of clear plastic, vinyl or PVC and not exceed 12″ x 6″ x 12.” It is important that all fans comply with these requirements, and we appreciate their efforts to cooperate with these security measures.

The NFL and team security departments work closely with stadium operation personnel and federal, state, and local law enforcement to provide a safe experience for the more than 17 million fans who annually attend NFL games. The NFL and its teams continually evaluate and improve our comprehensive security plan.
