The NFL is determined to play next week's Monday Night Football game between the Kansas City Chiefs and Los Angeles Rams despite significant concerns about the poor playing surface, according to league sources.

Moving the game from Mexico City's Estadio Azteca to Los Angeles remains an option.

"We are working closely with the field manager at Azteca Stadium and others to ensure that we have an NFL-quality surface for our game, and we are looking forward to kicking off in Mexico City on Monday night," league spokesman Brian McCarthy said.
