What happened: Inter Miami officially confirmed the signing of midfielder Casemiro, drawing a public welcome message from David Beckham. The celebration was immediately met with Major League Soccer launching a tampering investigation into the acquisition.

Why it matters: The league is reviewing the timeline of the transfer following a three-year agreement struck before his formal departure from Manchester United as a free agent. Any confirmed tampering violations could result in significant fines or roster mechanism penalties for the club.

What to watch: MLS has not established a public timeline for the conclusion of its inquiry into the transaction.
