Wow, and Thompson had been through many wars in his career prior to the Ferguson loss. I can even remember the fight being hard to watch watching it live. Thompson got absolutely dismantled and bashed every second of that fight and had multiple, nasty cuts where he painted the canvas red.
It's up there with Koscheck/Lytle as one of the most savage fights to watch just in terms of the many pints of blood spilled by one opponent. I knew these guys MUST have been feeling feint as they actually looked pale from the massive blood loss.
Weirdly enough, I don't think there's a rule for doctors evaluating blood loss during fights. They look for concussion symptoms, broken bones, vision and cuts where the blood runs into the eyes obscuring vision, but I can't recall in the many thousand MMA matches I've watched where a doctor has stopped the fight purely on blood loss alone. Blood loss can't exactly be measured in real time, but in regards to the Kos/Lytle fight, he literally stained multiple square feet of the canvas in blood, and even though he only absorbed some average GnP, he was woozy as hell when back on his feet. It was the first card my then GF watched (after me convincing her it was actually pretty safe as I was doing MMA at the time), and she was horrified.
Sacrifices to the JBGs come at a price apparently.
