NFL spokesman Brian McCarthy told ESPN's Adam Schefter on Monday night that the league is "working closely" with stadium personnel "to ensure that we have an NFL-quality surface" for the game.
But sources told Schefter that significant discussions are underway about whether the game will be played in Mexico City, Los Angeles or postponed, and that a decision is expected this week.
One source still expects the game will be played in Mexico City, according to Schefter, but another source said he thinks moving the game to Los Angeles is still an option that will be decided this week.
