Reports in Mexico stated El Tri had real concerns about the stadium's pitch, but U.S. Soccer says conditions will be playable.

SAN ANTONIO -- The most anticipated friendly in North America this year has been sold out for months, but reports emerged on Tuesday claiming the U.S. national team's clash with Mexico might not happen because of poor field conditions at the Alamodome.

But U.S. Soccer worked quickly to address claims from media reports from Mexico that suggested El Tri was ready to pull out of the friendly if the temporary grass field installed in the Alamodome was not improved.

"The field installation was not completed when the Mexico national team representative saw it on Monday," U.S. Soccer spokesman Neil Buethe said in a statement issued after inquiries from Goal USA. "Improvements have been made in the past 24 hours and the grounds crew will continue to provide maintenance in the lead up to tomorrow's match.

"The field will be in playable condition in time for tomorrow's match."

Mexico moved its scheduled Tuesday practice at the Alamodome and instead practiced at nearby Trinity University, where the U.S. trained on Monday. The U.S. has gone ahead with its scheduled training session on Tuesday evening at the Alamodome.

While Mexico national team coach Miguel Herrera and Hector Gonzalez Inarritu both expressed concern about the pitch, they also expressed optimisim that the field can be improved and the match should be able to proceed as normal.

"Not to play the game would be very drastic," Herrera said after training Tuesday. "I don’t have that much power in my hands to say, 'No, I don’t want to play,' because it isn’t just a soccer team, it’s a team that represents a country. It’s a sell-out, the media is here, television. It isn’t that easy to make the decision not to play."

The playing field is not expected to be at a top level for Wednesday's match, but the grass field is expected to be playable enough to not affect play or jeopardize the health of the players who will be competing in the latest installment of CONCACAF's biggest rivalry.
