With the Super Bowl only days away, U.S. Customs and Border Protection officials have announced that the agency has seized 10,710 fake National Football League jerseys at Los Angeles and Ontario international airport cargo facilities since the season began in September.

In a string of seizures from Sept. 8 to Jan. 25, CBP officers and import specialists assigned to cargo operations have seized 304 parcels containing counterfeit NFL team jerseys at LAX and ONT, CBP spokesman Jaime Ruiz said.

The combined estimated manufacturer’s suggested retail price of the merchandise is $847,000, he said.

“CBP officers and import specialists are highly specialized in product identification, detection and interception of trademark violators,” said Todd C. Owen, CBP director of field operations in Los Angeles. “Counterfeit sports apparel typically looks similar to brand name jerseys but are cheaper and of poorer quality.”
