The first leg of the Liga MX playoff semifinals matchup between Club America and Leon has been moved out of Mexico City due to pollution concerns from ongoing fires in the region.
The game at Estadio Azteca -- home venue of Club America -- had been already postponed from Wednesday to Thursday. The league announced that the game is now set to played at Estadio Corregidora in the city of Queretaro.
About 45 brush and grass fires were reported in Mexico City and its suburbs over the weekend, while dozens of fires are burning in surrounding states. Government officials had declared a pollution emergency Tuesday because of smoke from brushfires that has cast a pall over the city of 9 million people.
The extremely small particles that are choking the city reached over 1.5 times acceptable limits.
Queretaro is located about 136 miles from Mexico City. The league had said Toluca's Estadio Nemesio Diez was considered but that area is also affected by the smoke.
The second leg of the match is still scheduled for Sunday at Leon.
Monterrey beat city rivals Tigres 1-0 on Wednesday to take the first leg of the other semifinals series.
