Visa and Bank of America today announced that they’re giving away 10,000 Google Cardboard virtual reality headsets at Gillette Stadium in Foxborough, Massachusetts. These will go to lucky fans of the New England Patriots and allow them to watch a new video of the football team practicing.

These aren’t just any Cardboard headsets, mind you — they’re limited edition, according to a statement. Naturally, the sponsors of the giveaway have a motive: promoting the BankAmericard Travel Rewards Visa credit card.

But even if people can’t pick up one of the headsets, or if they don’t have an iOS or Android smartphone that supports Cardboard, they can still watch the (360-degree YouTube-based) video online, by visiting visa.com/bofa360.

Brands have begun turning to virtual reality for marketing purposes. The shoe company Tom’s, for example, produced a video showing employees offering free shoes to children in Peru.

Technology from Silicon Valley startup Strivr Labs is behind the new video of the Patriots, according to a statement. Previously, the Patriots and other football teams have looked to Strivr to help train their players.
