A civil suit filed in New Jersey state court accuses New York Giants insiders of passing off bogus collectibles and of framing a sports memorabilia dealer who ended up ensnared in a federal investigation.

Plaintiff Eric Inselberg, a former Giants business associate, alleges that quarterback Eli Manning and other players directed locker room staff to doctor helmets and jerseys to make them appear as though they’d been worn in games, and then moved them to dealers for sale to unwitting collectors.
