The NFL will beef up security at its stadium’s for this weekend’s games in response to the Paris attacks. In a statement released today, the league says, “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.” No specific threats against stadiums in the U.S. have been reported, the NFL says, so the increased police presence is just a precaution. The League also suggested that fans not bring bags to the games. CBS’s line-up of Sunday games begins at 1 pm ET with the Miami Dolphins and Philadelphia Eagles in Philly, followed by New England Patriots and New York Giants in NYC. NBC’s Sunday Night Football kicks off at 8:20 pm ET with the Arizona Cardinals vs. Seattle Seahawks in Seattle.
