The NFL’s announcement that four 2017 regular-season contests will be played in London isn’t necessarily bad news for Mexico City.

Sporting News has learned that the league may return next season by expanding its inventory of international games.

The NFL is still in the process of evaluating the situation, a source said. Last month, the league returned to Mexico City for the first time since 2005, when Oakland played Houston. The game was seen as a success both logistically and financially by the NFL with an easy sellout of 75,000-seat Azteca Stadium.

Besides Mexico City, Monterrey remains another potential host city because of the NFL’s popularity in that country.

London mayor Sadiq Khan had lobbied the NFL for four games in 2017 before the NFL staged its third matchup there this season between Cincinnati and Washington. All three London games, including Jacksonville vs. Indianapolis and Los Angeles vs. the New York Giants, were sellouts, as well.

The teams for next year’s London games will be unveiled Tuesday, but dates and stadium locations won’t be officially announced until 2017. The NFL has confirmed that New Orleans vs. Miami is one of the matchups.
