His team-mate, Jordi Alba, also left early in the first half (34d), which worried Argentine coach Tata Martino, who thought it was a muscle injury.
The newspaper quoted "Marca" Spanish Martino as saying after the end of the match, he does not believe that "there are muscle injuries" for Messi and Alba, noting that after talking with both players became "less pessimistic."
The Inter Miami coach admitted he was not considering their presence on Sunday against Orlando in the MLS and stressed that he is confident of their presence in the US Open final next Wednesday against Houston Dynamo.
"It's just fatigue, I don't think there's a muscle injury. I know we have a final, but it's impossible for them to go into the stadium if they're not in a position to do so."
It is noteworthy that the meeting between Inter Miami and Toronto ended in favor of Robert Taylor's comrades with four clean goals.
Inter Miami are currently in 25th place with 31 points, 28 points behind leaders Cincinnati.
