Michael Bisping has detailed how many times he fought 11 times with one eye after a hit which should have been career-ending.
In 2013, Bisping was hit with a vicious head kick by Vitor Belfort, knocking him out. At the time Belfort had been using a now-banned testosterone replacement therapy, more commonly known as TRT, which had given a clear physical advantage in the octagon.
Bisping would go on to suffer from eye issues for the remainder of his career, after the kick had given him a detached retina - fighting 11 further times, practically with one eye. Somewhat shockingly, he would fight just three months after the emphatic KO loss - defeating Alan Belcher at UFC 159, but after this his career was in jeopardy.
