Inter Miami announced Monday that Lionel Messi has been diagnosed with muscle fatigue and overload in his left hamstring [1].

The injury to the 38-year-old Argentine star [4] comes at a critical juncture for the club's campaign. Because Messi serves as the primary offensive catalyst for Inter Miami, his absence creates a significant gap in the team's tactical structure and scoring potential.

The diagnosis followed a match Sunday against the Philadelphia Union [2]. Medical tests indicated that the player experienced an overload associated with fatigue in the muscle, which is often a result of intense match play and accumulated physical stress [1], [3].

In a statement released by the club, Inter Miami said, "Lionel Messi has an overload associated with fatigue in his left hamstring" [1]. The club said, "Lionel Messi is experiencing muscle fatigue in his left hamstring" [2].

There is currently no fixed date for the player's return to the pitch. The club's medical staff will monitor his recovery through a series of evaluations to ensure the muscle has fully healed and can withstand the rigors of professional competition.

Inter Miami said, "His return will depend on his clinical and functional progress" [3]. The team has not specified how many matches the player is expected to miss while he undergoes rehabilitation.

The injury occurred during the contest with Philadelphia Union, leading to his departure from the game [2]. This type of soft-tissue injury is common in veteran athletes, though the recovery time varies based on the severity of the overload [3].
