What happened: Zackory Campagnolo moves to St. Louis CITY SC on loan through the remainder of the 2026 MLS season. Colorado receives an international roster spot in exchange for the 19-year-old goalkeeper.
Why it matters: International slots determine how many non-domestic players a club can carry, giving Colorado added roster flexibility. St. Louis adds teenage goalkeeping depth for the stretch run.
What to watch: Watch whether Colorado fills the slot and whether Campagnolo earns minutes in St. Louis.
