Lionel Messi's participation in the upcoming World Cup is now uncertain following his early exit from Inter Miami's match against the Philadelphia Union. The 38-year-old forward left the field in the 73rd minute after appearing to reach for his left hamstring. Despite walking off under his own power, Messi's immediate departure raised concerns regarding his fitness ahead of the tournament, which starts on June 11 across the United States, Canada, and Mexico. Argentina has not yet finalized its squad, but Messi is expected to be included as they defend their title. The team's first match is set for June 16 against Algeria. Messi has previously indicated he would only play if fully fit, and his absence could significantly impact Argentina's chances in the tournament. The forward has participated in five World Cups and is the only player to win the Golden Ball twice, showcasing his pivotal role in the team's success.
