MIAMI — Inter Miami confirmed Monday that Lionel Messi has a left hamstring issue, though did not say when the problem is expected to be cleared up.

And that adds a bit of intrigue for defending World Cup champion Argentina, which is scheduled to open its training camp for this year’s tournament on June 1 in Kansas City.

Messi underwent testing on Monday — 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.”

Typically, the timeframe for recovery from such issues is varied depending on the severity.
