MLS Launches Tampering Probe into Inter Miamis Casemiro Signing
When Inter Miami CF announced the signing of Brazilian midfielder Carlos Henrique Casimiro, Major League Soccer (MLS) immediately began scrutinizing the deal for potential rule violations.
The 34‑year‑old midfielder, who departed Manchester United after the 2025‑26 campaign, will stay with the Floridian club through the end of the 2027 MLS season, with an option to extend until June 2029. Inter Miami revealed that it secured Casimiro’s discovery rights from the Los Angeles Galaxy as part of a settlement. The Galaxy, in turn, said it had reached an agreement with Inter Miami but would keep the settlement’s terms secret until the investigation concludes.
MLS has stated it is collecting all relevant information and will withhold further comment until the review is finished. The league noted that, although Inter Miami and the Galaxy have settled the discovery‑rights dispute, the details will only be released after the tampering investigation ends.
Discovery rights are a cornerstone of MLS roster rules. Each club may hold rights for up to five players, preventing other MLS teams from contacting a listed player during negotiations. Rights can be transferred or sold, but the transfer must follow league procedures. The investigation centers on whether Inter Miami bypassed the Galaxy’s rights or otherwise violated MLS rules during the signing.
Casimiro’s arrival follows a high‑profile transfer saga. He announced in January that he would leave Manchester United by mutual consent after the 2025‑26 season. Having joined United in 2022 from Real Madrid—where he won five Champions League titles—he made 160 appearances, scored 26 goals, and provided 14 assists, while also winning the FA Cup and EFL Cup.
The signing is significant for Inter Miami, which has recently added other high‑profile players such as Lionel Messi and Rodrigo De Paul. Co‑owner David Beckham welcomed Casimiro’s arrival, describing him as a “winner” with a “tremendous career.” Casimiro will join teammates Sergio Reguilon, Messi, and De Paul.
MLS has a history of scrutinizing Inter Miami’s transfer dealings. In 2021 the club was fined $2 million after signing French midfielder Blaise Matuidi from Juventus. The fine was imposed because the club’s compensation for Matuidi exceeded the limits set for designated players, effectively giving Miami four designated players instead of the maximum of three allowed under MLS rules.
The Designated Player Rule, introduced in 2007, allows teams to sign up to three players whose wages or transfer fees exceed the league’s salary cap. The rule has been used by MLS clubs to attract international stars, most famously when David Beckham joined the Los Angeles Galaxy in 2007.
The outcome of the tampering investigation remains uncertain. MLS officials have not yet released a decision or any potential penalties. Inter Miami and the Galaxy have agreed to keep settlement details confidential until the investigation concludes. The league’s statement indicates that no further commentary will be made until the review is finished.
For now, Casimiro is expected to begin training with Inter Miami ahead of the 2026 MLS season. The club’s roster will be evaluated for compliance with MLS roster rules, including international slots and designated player limits. The investigation will also examine whether Inter Miami’s transfer process adhered to league protocols regarding discovery rights.
The investigation’s conclusion could have implications for MLS transfer policy, the enforcement of discovery rights, and the broader governance of player movement within the league. Until the league releases its findings, the situation remains in limbo, with Inter Miami and the Galaxy awaiting the final outcome.
