On June 23, 2016, the UK voted to leave the EU and on January 31, 2020, the UK formally left the EU although it remained in the European Union Customs Union and European Single Market until the end of 2020. A spokesperson for the NFL said that it was working closely with its UK offices and "monitoring" the situation closely. Nonetheless, some speculation has led to keep NFL owners on alert if the UK goes into a recession following an exit from the EU.
