I really don't understand how anyone who sees the video of this moment would question it. It's clear that Dirrell slipped while throwing a punch. His leg clearly slides on the canvas in a wet corner no less. He was down for at least one second befroe Abraham stepped forward and delivered a underhand hook that landed on dirrell's jaw and twisted his neck. Watch the tape and stop making excuses. AA clearly deserved what he got.
Euro's / Brits can spot faking a mile away..we see it multiple times a week in football when overpaid fairys throw themselves at the ground tol win the refs favour....Dirrell faked it because he was running on empty and was scared he would get tagged... How anyone with a fully functional brain can watch the KO and not be at LEAST suspicious amazes me nut
