Former world cruiserweight title challenger Ovill McKenzie revealed on Friday a heart condition has called a halt to his career prematurely.

The 36 year-old ‘Upsetter’ last fought in October 2015 when challenging for the IBF title, just coming up short in a draw on Argentinian soil against Victor Ramirez.

A shot against IBO belt holder Marco Huck was arranged for McKenzie this year, although a red flag from doctors forced the Derby man to reassess his situation.

After some weeks of deliberation and gathering test results, McKenzie’s worst fears are now confirmed.

“It is with great sadness that I announce that I am retiring from boxing. I have been diagnosed with a heart condition. I can no longer pursue my dream of being a world champion,” said McKenzie.

“I would like to take this time to thank everyone from my team to the fans.

“As disappointed I am about the situation, it’s been a great pleasure getting to perform for you all and have to keep my chin up.”
