The NFL made a strong push to expand its international footprint this season and could take yet another significant step this week.

Team owners are convening in Irving, Texas, on Tuesday and Wednesday for a special league meeting. A source confirmed to Front Office Spots that the agenda includes a vote, expected on Wednesday, to require all 32 clubs to play one designated home game outside the U.S. every four years. Right now, teams are required to do so once every eight years. Sports Business Journal initially reported the news.

The NFL played five international games this fall — three in London and two in Frankfurt — and is exploring the possibility of playing future games in Madrid and Sao Paulo, Brazil, along with plans to eventually return to Mexico City. NFL commissioner Roger Goodell has made multiple comments about expanding in Europe and even hinted at playing a Super Bowl in London.
