At the onset of this video from Al Sadd's 2-0 win over the Suwon Samsung Bluewings, Choi Sung-hwan of the latter's head gets jacked up. Before trainers can even finish wrapping Choi's dome, Al Sadd scores a goal (at the 1:18 mark). From there, the discord ranges from yappy to shovey until roughly the 4:30 point, where things turn all-out fracas.

After a goalless first period, Niang opened the scoring in the 70th minute thanks to a deflected shot from outside the box before Al Sadd caught Suwon off guard with a quickly-taken free-kick and the former Marseille striker rounded keeper Jung Sung-ryong to double the lead.

That incensed Suwon, who felt the visitors were guilty of unsporting behaviour following a head injury to Choi Sung-hwan, and chaotic scenes ensued as tempers frayed with both sides coming to blows.
