Just 31 days after winning the UFC’s middleweight title in a remarkable return, Georges St-Pierre has vacated his belt.

In a statement provided by the UFC, St-Pierre said:

My fight at UFC 217 was one of the greatest nights of my life but I now need to take some time to focus on my health. Out of respect to the athletes and the sport, I don’t want to hold up the division. I will be giving up my belt and once I’m healthy I look forward to working with the UFC to determine what’s next in my career.

St-Pierre was diagnosed with ulcerative colitis last week and ultimately lead the former two-division champion into vacating his title.

With St-Pierre no longer champion, Robert Whittaker has been formally promoted to undisputed middleweight champion after claiming an interim championship against Yoel Romero at UFC 213.

As a result of Whittaker’s promotion, the UFC has acted swiftly to resume normality in the 185 lbs division and ‘The Reaper’ will now look to defend his title for the first time at UFC 221 against Luke Rockhold.

UFC 221 will take place in Whittaker’s home country of Australia and will mark the UFC’s debut in Perth.
