Former WBO featherweight champion Colin McMillan could be forgiven for being sour.

Just when he had the world at his feet, as the reigning champion, he lost his crown in his first defence when he suffered a dislocated shoulder. Things changed from that moment.

But McMillan has retained his highly positive disposition and is one of boxing's good guys. He had a fascinating career, trying to forge his own path, working with the late author Jonathan Rendall as an advisor, being guided by Terry Marsh and then, afterwards, becoming an advisor to Audley Harrison.

In his own fighting career, there were big nights against big names when he was being touted as the next big thing and then came the disappointment of the injury that curtailed his charge. There were battles with the powers that be, battles with himself and battles with his shoulder. This is an incredible story.
