They didn't just happen to cross paths after the game, Gregory stalked Aboushi and kept yapping at him, then as Aboushi was shaking hands with another player Gregory punched him in the head area (helmet facemask) and Aboushi retaliated with a shot to Gregory's chest area.
My friends who are cowboy fans were so happy he left. They called him a cancer and is always on the edge of doing something stupid.
