Tereshin made his name by pumping his arms with synthol to increase their size to a freakish size. And his one-foot-wide biceps proved to be his Achilles heel as he was taken down and finished with an armlock that left the big-armed Russian in unbearable pain as he tapped out his submission

Tereshin, whose Instagram account boasts 444,000 followers, is something of a cult figure on social media, with his decision to step into the cage keenly followed by his fans online.

Unfortunately, Tereshin, who admitted pre-fight that he was "not a fighter", found himself unable to cope with having one of his huge arms trapped on the mat.
