The altercation occurred in the injury time of the match, when Messi and Philadelphia Union player Quinn Sullivan got into a heated exchange. Sullivan was given a red card after another incident in the final stage of the match. The exact amount of Messi's fine is not known.

The incident is just one of several notable moments from the match, which saw Messi score his first goal since the death of his father Jorge Messi. The goal was a significant one for the Inter Miami player, who celebrated by pointing two fingers to the sky. However, the match ultimately ended in defeat for Inter Miami, who lost 1-2 and have not won in three games.

The altercation between Messi and Sullivan has raised questions about the behavior of the two players. While the exact circumstances of the incident are not clear, it is evident that both players were involved in a heated exchange. The fine imposed by MLS is a clear indication that the league takes such incidents seriously.

The incident has also highlighted the emotional toll that the death of his father has taken on Messi. The goal he scored in the match was a significant moment for the player, and his celebration was a testament to the impact that his father had on his life.
