Lionel Messi, the renowned forward for Inter Miami, is currently sidelined due to muscle fatigue in his left hamstring. This injury occurred during a high-scoring match against the Philadelphia Union, where he requested to be substituted in the 73rd minute. Following further medical assessments, Inter Miami confirmed that the injury results from an overload linked to muscle fatigue. The precise timeline for Messi's return to training remains unclear, as it depends on his recovery progress. This situation arises just before Argentina's preparations for its World Cup title defense, with a training camp scheduled in Kansas City. Argentina's first group-stage match is set against Algeria on June 16, 2026, followed by games against Austria and Jordan. Messi, who played a pivotal role in Argentina's 2022 World Cup victory and was awarded the Golden Ball for best player, may need additional rest before rejoining the national team or resuming training.
