Inter Miami announces it has signed Brazil midfielder Casemiro, but Major League Soccer says it is investigating allegations that the club may have breached league rules in the process. Multiple outlets report that the Brazil international, 34, joins Inter Miami as a free agent and signs through the end of the 2027 “sprint season,” with an extension option that would keep him in the club until the 2028-29 MLS season. Several reports also specify that Casemiro appeared in all five of Brazil’s matches at the 2022 World Cup, scoring once.

The core issue raised by MLS relates to Casemiro’s discovery rights, which were held by the LA Galaxy. Under MLS rules, those rights would typically affect how and when other clubs can negotiate with a player. According to reports, a settlement was reached that allowed Inter Miami to complete the deal, but MLS is still reviewing whether any tampering occurred. BBC Sport and The Athletic describe the investigation as an MLS probe into the circumstances surrounding how Inter Miami acquired the player.
