In the 15-second clip, two Ravens fans taunted Jackson by saying, "I'm so sorry for you."
The remarks did not sit well with Jackson as he uncapped a bottle of water and squeezed it in their direction. In a Wednesday press conference, his brother Patrick Mahomes spoke on the incident, KSHB reports.
"Obviously, it's something we don't want to necessarily do," Patrick said.
"There were things that were said to him and Brittany (Patrick's fiancée Brittany Matthews) that you don't see in the clip," the sibling continued. "He's been good at trying not to respond to that stuff. He takes a lot and he's usually pretty good at it and he'll learn from it and try to stay away from those people as best he can."
