Josh Yaro Joins Athletic Club Boise on Loan for 2026 Season

St. Louis CITY SC defender Josh Yaro has joined USL League One side Athletic Club Boise on loan for the remainder of the 2026 season, drawing a line under a significant early chapter in the expansion club’s story.

The 31-year-old center back has been part of the CITY setup since 2022, arriving before the first team ever kicked a ball in MLS. He anchored the back line for CITY2 during that inaugural campaign, helping the reserve side capture the first-ever MLS NEXT Pro Western Conference title and setting an early standard for the club’s on-field identity.

From there, Yaro stepped into the senior squad in 2023 as St. Louis CITY SC burst onto the MLS scene. He never carried the marquee status of some of the club’s headline arrivals, but inside the building he became one of the constants: a reliable squad defender, a voice in the dressing room, and a player the staff trusted to plug gaps when injuries and suspensions hit.

“Josh has been with the club from the beginning and has always been a great teammate, stepping up whenever needed both on and off the pitch,” Sporting Director Corey Wray said, underlining just how deeply woven Yaro has become into the club’s fabric.

The move to AC Boise is about opportunity. At 31, Yaro needs games, not cameos. St. Louis, stacked with defensive options and chasing MLS ambitions, can’t guarantee him the consistent minutes that shape a season. Boise can.

Wray framed the loan as a reward as much as a reset. “He has embraced the city and consistently made an impact through numerous community initiatives, which speaks to the person he is. We are excited that he now has an opportunity to get consistent minutes in a competitive team and wish him and AC Boise the best for the remainder of the season.”

For St. Louis, it’s a pragmatic decision. For Boise, it’s a statement. They’re not just adding an experienced defender; they’re bringing in a player who has lived the demands of a winning locker room and helped build a culture from scratch.

Yaro leaves with a Western Conference medal from CITY2, a place in the club’s short but eventful history, and a chance to prove he can still command a back line week after week. The next few months in Idaho will show whether this is a late-career detour—or the platform for one more surge.
