Twenty-Four Players Called For USMNT BioSteel January Training Camp To Kick Off 2026 FIFA World Cup Cycle

USA Starts Journey Against Serbia on Jan. 25 at Banc of California Stadium in Los Angeles and Colombia on Jan. 28 at Dignity Health Sports Park in Carson; Eleven Players Receive First Senior Team Call-Up, 13 Seek First Cap

CHICAGO (Jan. 18, 2023) – At the start of the 2026 FIFA World Cup cycle, 24 players have been called to Southern California for the annual U.S. Men’s National Team’s BioSteel January training camp. A total of 13 players are seeking their first full international cap, while five players lend veteran experience as they return from the USMNT’s successful run at the 2022 World Cup.

The training camp will kick off Jan. 21 before the USMNT faces fellow 2022 World Cup participant Serbia on Wednesday, Jan. 25 at Banc of California Stadium in Los Angeles (10 p.m. ET; HBO Max, Universo, Peacock, Telemundo App) and South American power Colombia on Saturday, Jan. 28 at Dignity Health Sports Park in Carson, Calif. (7:30 p.m. ET; TNT, Telemundo, Peacock, Telemundo App). 

USMNT assistant coach Anthony Hudson will lead the training camp while fellow World Cup assistant B.J. Callaghan and Under-20 Men’s Youth National Team head coach Mikey Varas will serve as assistant coaches.

“We are thrilled with the group of players we’ve been able to put together for this camp,” Hudson said. “The annual January Camp gives us a chance to look at some real high potential young players as well as some dual nationals we have been following. The focus has been on identifying positions within our team that need more depth. We are also leaning on some of our veteran players for their experience on the field as well as to socialize the younger players into the incredible culture we have built within the squad. We know from history that many players who get their first national team opportunity in this window go on to make a World Cup roster, so we want them to make the most of it.”

With the match dates falling outside of the designated international calendar, clubs are not required to release players for national team duty. The January Camp typically consists largely of U.S.-based players who are not in season.

Dating back to 1999, 30 players who have debuted or earned their second cap during the USMNT’s first camp of a calendar year have gone on to make a FIFA World Cup roster. From the USA’s squad at Qatar 2022, nine players earned their first or second cap during a January camp match, including captain Tyler Adams, forward Brenden Aaronson, defenders Walker Zimmerman and Tim Ream and starting goalkeeper Matt Turner. That figure also includes five members of the 100-cap club: Jozy Altidore, DaMarcus Beasley, Carlos Bocanegra, Clint Dempsey and Landon Donovan.


The USMNT’s January training camp roster is traditionally filled with rising talents getting their first looks with the senior team and this year’s squad is no different. Eleven players have earned their first USMNT call-up -- goalkeeper Roman Celentano, defenders Julian Gressel, Jalen Neal, Sam Rogers and John Tolkin, midfielders Paxten Aaronson, Aidan Morris and Alan Soñora plus forwards Emmanuel Sabbi, Brandon Vazquez and Alejandro Zendejas. In addition, goalkeeper Gaga Slonina and defender DeJuan Jones join the aforementioned 11 in seeking their full international debut against Serbia and Colombia. Five other players have six or fewer USMNT appearances -- defender Jonathan Gómez, midfielders Paxton Pomykal and Eryk Williamson plus forwards Cade Cowell and Matthew Hoppe.

The young, uncapped players come with plenty of experience in the U.S. Men’s Youth National Teams program. Last summer, Aaronson, Cowell and Neal helped lead the USA to a third-straight Concacaf U-20 Championship, a berth to the Olympics for the first time since Beijing 2008 and a spot in this summer’s FIFA U-20 World Cup. First-time call-ups Vazquez and Zendejas represented the USA at the 2015 U-17 World Cup, while Sabbi was a part of the U.S. team at the 2017 FIFA U-20 World Cup. 


In addition to the young talent getting an opportunity this month, five players return from the USMNT’s successful run at the World Cup -- goalkeeper Sean Johnson, defenders Zimmerman and Aaron Long, midfielder Kellyn Acosta and forward Jesús Ferreira. Zimmerman played a key role on the U.S. back line, appearing in every match and making a critical goal line clearance late in the USMNT’s knockout round-clinching victory against Iran. Acosta made two substitute appearances in Qatar and Ferreira started in the Round of 16 match against Netherlands.


After the condensed World Cup qualifying schedule featured three Octagonal matches for the USMNT during January/February 2022, the USA returns to the passionate soccer community in the Los Angeles area to launch its four-year run up to hosting the world’s biggest sporting event - the 2026 FIFA World Cup - alongside Canada and Mexico.

The USMNT has played in California 114 times, more than any other state, with 43 of those matches taking place in Carson and Los Angeles. USA-Serbia marks the USMNT’s first game at LAFC’s Banc of California Stadium, while the U.S. is 12-2-3 at Dignity Health Sports Park all-time and 11-7-9 in matches played in Los Angeles proper. SoFi Stadium in Inglewood, Calif. is one of 11 U.S. host venues for the 2026 World Cup.


The match on Jan. 15 at the Banc is just the fourth meeting all-time between the USMNT and Serbia, with the U.S. posting a 0-2-1 record since their first meeting against then Yugoslavia at the 1956 Olympics in Sydney. The U.S. also dropped a tight 1-0 loss at the 1998 FIFA World Cup in France.  The nations played to a scoreless draw to kick off the USA’s 2017 schedule on Jan. 29 at Qualcomm Stadium in San Diego.


The USA will face a Colombia squad hungry to kickstart the 2026 World Cup cycle after missing the tournament for the first time since 2010. The U.S. will look to earn its first victory against the South American squad since March 2005, a 3-0 win in Fullerton, Calif. One of the USMNT’s most memorable World Cup victories came against Colombia in Southern California during the 1994 World Cup, a 2-1 win at the Rose Bowl in Pasadena featuring a goal from current U.S. Soccer Sporting Director Earnie Stewart.
