Georges St-Pierre not sure if body can handle middleweight defense

Georges St-Pierre, who returned to the Octagon last month at UFC 217 after a four-year layoff to claim the middleweight title, told TSN today that he is unsure whether he will defend the belt. The decision stems from the stress he put on his body to gain enough weight to get to 185 pounds and compete with then-champion Michael Bisping.

It was revealed earlier this week that St-Pierre has been dealing with colitis, which refers to inflammation of the colon and can cause abdominal pain, cramps and diarrhea.

"We'll talk about it, but I'm not sure if I compete I will go back at 185," St-Pierre (26-2) said. "I don't think so.

"Of course, in terms of weight, if I want to go back to compete at 185, I will. Obviously eating, like I did what I did, I learned from my mistakes. I don't think it's a good thing to do, force myself to eat to gain muscle mass.

"I've always been against performance-enhancing drugs, and I did it the natural way," St-Pierre said. "There is no easy way. I did it the hard way, and it was to gain weight and to maintain my muscle mass, and it was very hard, and it was not healthy. I think the body has a natural weight it can perform at its best athletic ability, and for me, the weight that I am now is my perfect weight."

St-Pierre's contract reportedly stated that if he won the belt, he would need to defend it against interim middleweight champion Robert Whittaker. Last week, UFC President Dana White told media he would be "super-pissed" if St-Pierre refused to defend the title.

The Montreal, Quebec, native, who spent most of his career at welterweight (170 pounds), is arguably the best mixed martial artist ever. He claimed the welterweight belt in 2007 and defended it successfully nine consecutive times. He has won 13 fights in a row.
