MLS started an inquiry on a recent Wednesday into the Miami side for possible tampering.

The action comes after the club brought in Casemiro on a free from Manchester United.

League leader Don Garber sent an written message about what comes now.

Inter Miami moved pieces around and schedule, which came up in midweek reports.

The team confirmed the Casemiro move but declined comment to tampering accusations.

League rules usually forbid contact with existing deals before set periods, and any offense can trigger a formal review.

The investigation will likely review communications between the club and Casemiro's camp during the periods in question.

Officials have not set a timeline for the outcome, and the league plans updates when ready.

Inter Miami stays active through the current run while the matter develops, and supporters pay attention for any updates.
