United States men's national team manager Gregg Berhalter has named a 26-man, Major League Soccer-heavy roster to a training camp ahead of a Dec. 18 friendly against Bosnia & Herzegovina.

Players will begin reporting to camp in Carson, Calif. on Dec. 5. The camp is being held ahead of a trio of World Cup qualifiers starting in late January, and is intended to keep MLS players fit now that the offseason has begun for most of them.

The match against Bosnia falls outside of a FIFA international fixture date, leaving players who are still in-season largely unavailable.

"It's been a great year for the group and our objective is to finish the year with a strong performance against Bosnia & Herzegovina," Berhalter said. "As we look towards 2022, this camp gives us the opportunity to see some new faces and allows our core domestic players to maintain their fitness levels."

The group is highlighted by MLS Defender of the Year Walker Zimmerman of Nashville SC, and MLS Goalkeeper of the Year Matt Turner of the New England Revolution.

Among recently called up players who won't make the trip include Orlando City SC striker Daryl Dike and Atlanta United FC defender Miles Robinson.

Speaking to reporters after the squad selection, Berhalter said that Dike was "beat up. He needs recovery."

The roster also contains 12 uncapped players. Of the 26 players called in, five play outside of MLS, including two who played last season in the USL Championship in Louisville City defender Jonathan Gomez and defender Kobi Henry of recently crowned title-winners Orange County SC.

Gomez is the latest dual national to be involved in a tug-of-war between the U.S. and Mexico squads, having already represented both countries at youth level. He recently secured a transfer to LaLiga side Real Sociedad, and will join them officially from Jan. 1. The other non-MLS players are Roma defender Bryan Reynolds, Internacional midfielder Johnny Cardoso and Bayern Munich II forward Taylor Booth.

There is also a recall for New York Red Bulls defender Aaron Long, who missed most of the 2021 MLS season due to a torn Achilles tendon.
