The United States is confident that Wednesday's friendly will go ahead as planned depite Mexico's concerns over the pitch at the Alamodome in San Antonio, Texas.
On Tuesday, a report in Medio Tiempo said that Hector Inarritu, the director of the Mexican Soccer Federation, had thoughts of refusing to let his country play after seeing the condition of the field, which consists of temporary grass installed over concrete.
In response to the report, U.S. Soccer spokesman Neil Buethe said, "The field will be in playable condition in time for tomorrow's match."
Buethe added that grounds crew would continue to work on field before Wednesday's 8:30 p.m. ET kick-off time.
"The field installation was not completed when the Mexico National Team representative saw it on Monday," Buethe said."Improvements have been made in the past 24 hours."

Mexico's training session on Tuesday was moved from the Alamodome to Trinity University because of concerns about the pitch, although Inarritu remained cautiously optimistic that the organisers will improve the playing surfacing and the game will go ahead.
"If the conditions really are deplorable and put the players at risk it will be impossible, but we have to think positively that there won't be any problem," Inarritu said.
Manager Miguel Herrera also said that pitch would make for a poor situation for both teams.
The 60,000-seat Alamodome, located 150 miles from the U.S.-Mexico border, is sold out for Wednesday's game.
Mexico previously played South Korea at the Alamodome in January 2014, winning 4-0.
