MEXICO CITY - Mexico's under-23 side completed a four-day training camp in the country's capital Wednesday, one of several preparation exercises among the eight qualified teams as they ready for next month's CONCACAF Olympic qualifying.

Manager Luis Fernando Tena will re-gather the team Sunday following the regular Mexican league matches for another four-day training stint before facing second-division side Neza on Wednesday.

Other activity includes Trinidad conducting a camp with 24 players in preparation for a Thursday match against Guyana; El Salvador will begin a four-day program Sunday before it faces Puerto Rico on February 22; and Panama travels to Colombia on Friday for a six-day tour including matches against Independiente and Atletico Nacional.

The United States, which trained for 18 days in January - its third gathering under new coach Caleb Porter, will assemble once more on Sunday in Frisco, Texas, before facing Mexico February 29 at FC Dallas Stadium.

Tena, who will muster his side on February 26 for the match against the United States, says it will be a month before he decides on his final roster for the March 22-April 2 qualifying in Nashville, Tennessee; Los Angeles and Kansas City, Kansas.

"The definitive list will be announced two days before the first match, in other words March 21," he said. "There are others who are not here now but have been on other occasions, others that aren't here because of injuries, the others have to keep on working in case an opportunity presents itself."
