NEW YORK (AP) — Investigators have seized more than $21.6 million in knockoff souvenir football jerseys, caps and other merchandise, shut down illegal websites and made dozens of arrests in a crackdown on Super Bowl counterfeiters, authorities said Thursday.

The seizures and arrests were announced at a Manhattan news conference where NFL and law enforcement officials displayed fake Payton Manning and Russell Wilson jerseys — complete with knockoff Adidas labeling — Broncos and Seahawks hats, Super Bowl T-shirts and other goods made to look like official NFL gear.
