ALBANY, N.Y. (AP) An official says New York authorities are investigating whether the NFL is engaging in anti-competitive practices on its ticket-selling website.

The investigation is part of a larger probe by state Attorney General Eric Schneiderman into high event ticket pricing.

Schneiderman released a report Thursday that criticizes ''price floors'' for tickets, particularly by sports leagues including the NFL.

The report says many NFL teams encourage or even require ticket holders to use Ticketmaster's NFL Ticket Exchange platform, where the seller is prohibited from cutting the price below face value. That prevents lower prices when demand drops.

An official with knowledge of the investigation says Schneiderman's office is investigating and wants the price floor removed. The official wasn't authorized to discuss it publicly and spoke on condition of anonymity.

A call to the NFL was not immediately returned.
