U.S. U-23 coach Caleb Porter called 19 players into the squad which will compete in the upcoming Olympic qualifiers at LP Field next week.
The MLS-heavy squad is headlined by Freddy Adu, Juan Agudelo and Brek Shea, who have all spent time with the senior national team. Shea most recently started in the 1-0 US victory over Italy.
Porter has until March 20 to finalize his 20-man roster. Because Olympic qualifiers do not fall on FIFA international fixture dates, clubs are not required to release players. Speculation about the final spot centered around Alfredo Morales, a central defender who plays for Hertha Berlin in Germany and Dilly Duka, a midfielder for the Columbus Crew, who pulled a hamstring in his club's season opener on Saturday. U.S. Soccer confirmed late on Monday that a player had been called in but withdrew due to injury. An MRI on his hamstring was negative.
The team will assemble in Nashville Tuesday to begin preparations.
The U.S. will open group play with Cuba on March 22 followed by Canada on 24th and El Salvador on the 26th. All three games will be played in Nashville.
