Increased security on Sept. 11 at sporting events

The Redskins host the New York Giants this Sunday at FedEx Field.

NEW YORK (AP) — From bomb-sniffing dogs to pat-downs of fans, security will be tight at 13 NFL games and the U.S. Open tennis tournament on Sunday, the 10th anniversary of the 9-11 terrorist attacks.

The two men in charge of safety at those events say any extra efforts, coordinated with the FBI and local police, are not so much a result of Sunday happening to be Sept. 11 but rather because of what happened on that date in 2001. Changes were made in the aftermath of the attacks to protect people at various sports sites.

Jeffrey Miller, the NFL's chief security officer, and Michael Rodriguez, the U.S. Open's director of security, say they are in regular contact with the Department of Homeland Security and, as of Wednesday morning, had not been informed of any specific, credible threats to their arenas.

The stepped-up security measures will be in place in Landover on Sunday, where the Washington Redskins will open the regular season with a game against the New York Giants.
