US Under-23 Men's National Team head coach Andi Herzog has named 19 players to the roster for the 2015 Toulon Tournament, including five from MLS; NYRB II's Dan Metzger; and Sounders Academy product Jordan Morris. The tournament runs from May 27-June 7 in the south of France.

World Cup veteran Julian Green was also named to the roster following a disappointing year on loan with Hamburg in the Bundesliga.

Herzog will make one as-yet unnamed addition to complete the 20-player roster, which will officially be submitted on Tuesday evening.

"Toulon is one of the most prestigious tournaments in the world at this age level, and we're fortunate to have the opportunity to compete against some of the top teams in the world," said Herzog. "Having seen matches here many times before, I know the type of talent we will face. This is huge for us as we get ready for qualification this October, and is another step in the development of our players in international competition."

The tournament was first held in 1967 and became an annual affair in 1974, often contested with U-20 rosters.

The best the US have ever placed was third, back in 1989. The most recent US trip to Toulon was in 2013, when they went 1-0-3 in the group stage with losses to France, Colombia and South Korea and a win over DR Congo.
