US coach Piotr Nowak has called 23 players to IMG Academies in Bradenton, Florida for a week-long training camp that begins on Saturday.

It will be the final chance for these players to secure a spot on the squad that will compete at the CONCACAF Olympic qualifying tournament from March 11-23.

All of the players called up are professionals, which is a big change from the last camp when nine of the 24 players were amateurs in college. Thirteen of the players called up were at the last training camp.

Nineteen of the 23 players called up are currently on MLS teams. This includes Chance Myers and Dominic Cervi - who were selected 1st and 12th, respectively, in the MLS SuperDraft last week. The four players who do not play in MLS are currently in Mexico, Germany, Denmark and Sweden.

"With the qualifying tournament approaching quickly, this is an important camp for us to train and evaluate players," Nowak told ussoccer.com. "Having another chance to train in Bradenton will be valuable as we prepare for very challenging Olympic qualifying games in nearby Tampa."
