What happened: The completed move follows an agreement in principle reached Aug. 3. Herrington had joined Colorado in January on a contract through 2029, with a club option for 2030.
Why it matters: The fee sets a Colorado club record and an MLS record for a center back. The departure removes an 18-year-old 2026 MLS All-Star from the Rapids' back line.
By the numbers: The package includes $17 million guaranteed and $6 million in add-ons. The fixed portion accounts for 73.9% of the maximum value.
What to watch: The add-on triggers will determine how much of the remaining $6 million Colorado receives.
