Major League Soccer said Monday that Montreal midfielder Matko Miljevic has been sacked for "engaging in conduct detrimental to the league."

A brief statement from MLS said the 22-year-old had his contract terminated following reports he violated league rules by playing in an amateur league using a fake name.

Reports in Canada last week said Miljevic had been banned from an amateur league in Quebec for punching another player in the face during a game.

Miljevic reportedly used a false name to play in the indoor league in a breach of his MLS contract.

MLS did not go into details of Miljevic's alleged offences in a brief one-sentence statement released Monday.

"Following an investigation, Major League Soccer has terminated the contract of CF Montreal midfielder Matko Miljevic for engaging in conduct detrimental to the league and violating his Standard Player Agreement," MLS said.

Miljevic, who was born in Miami to Argentine parents before moving back to Argentina with his family as a child, came through the Boca Juniors academy before later starting his professional career with Argentinos Juniors.

He joined Montreal in 2021, making 35 appearances for the club with two goals.
