NFL owners approved rule changes on Tuesday that will enable in-stadium retail sportsbooks to remain open on home game days, a league spokesman told .
At the moment, there is only one operational brick-and-mortar sportsbook inside an NFL venue: the Fanatics Sportsbook at FedEx Field in Landover, Maryland.
Fanatics opened the retail sportsbook on Jan. 20, one day before the start of the NFL divisional playoff round. FedEx Field has been the home of the NFL's Washington Commanders (formerly Redskins) since 1997.
