What happened: The September-October assignment places Miller with the United States U-20 Men's Youth National Team during the fall international window. It follows his June call-up to a U.S. U-19 camp.

Why it matters: Another youth national-team selection keeps Miller in the U.S. player pool as the 2026 calendar moves into its final months. The move from a summer U-19 camp to a fall U-20 camp gives him a look with an older age group in the same year.

What to watch: Camp roster details and any Spain schedule are the next markers to watch once the window opens.
