What happened: Sporting Kansas City acquired two international roster slots through separate trades, one with the Philadelphia Union and one with the Seattle Sounders FC. The additions give the club extra roster flexibility as MLS's midseason transfer window remains open for new signings.

Why it matters: International slots let clubs carry non-homegrown players without triggering a roster crunch, making them valuable currency around trade deadlines. The extra room gives Kansas City more space to register international signings without shedding other roster spots.

What to watch: How Kansas City deploys the two slots will surface in its next roster and registration filings, along with any further summer additions.
