It was earlier reported PSG's manager Christophe Galtier suspended Messi for two weeks over an unauthorized trip to Saudi Arabia as part of his contract with the Saudi tourist office.
Messi will be banned from playing or training with the team for two weeks, and his pay will be docked during his suspension. The forward will miss the Ligue 1 matches against Troyes on May 7, and against Ajaccio on May 13, to return for the match against Auxerre on May 21.
French media reported management's decision not to extend Messi's contract was made in an aftermath of his unauthorized trip.
Messi joined PSG in summer 2021 in free agency on a two-year deal after his departure from Barcelona. His contract with PSG expires this summer.
Messi won the World Cup in Qatar in December 2022 for the first time in his career and was chosen the best player of the championship.
