Inter Miami have confirmed that Lionel Messi has a left hamstring issue, one that has popped up about a week before defending World Cup champions Argentina are set to begin their training camp for this summer's title defence.
And the events of Sunday and Monday surely add at least a bit of intrigue to Argentina's plans.
Messi underwent testing on Monday (Tuesday AEST) — which almost certainly means an MRI exam, though the team did not divulge what procedures were involved — and was ultimately diagnosed with "an overload associated with muscle fatigue in his left hamstring" that kept him from finishing Inter Miami's match against Philadelphia.
