United States international Jack McGlynn as joined the Houston Dynamo on a permanent deal from the Philadelphia Union, the two teams announced on Monday.
McGlynn, 21, becomes just the second cash-for-player trade in MLS history after Dejan Joveljić joined Sporting Kansas City from LA Galaxy on Sunday. The new type of transfer was only announced as part of the 2025 MLS roster rule changes on Jan. 14.
Houston has paid $2.1 million for McGlynn's services, with the Union retaining a sell-on percentage of any future fee should the midfielder move again.
McGlynn came through the youth ranks at Philadelphia and made his MLS debut in April 2021.
He was called up to the January 2024 USMNT camp and made his debut on Jan. 20 that year in a friendly loss against Slovenia. McGlynn scored his first goal for the senior national team on Jan. 28 this year, opening the scoring in a 3-1 win over Venezuela.
