Georges St-Pierre's return to mixed martial arts (MMA) could be getting even bigger.The Canadian reigned as the greatest welterweight champion of all time after having successfully defended the strap nine consecutive times. He called it a career after a controversial split decision win over Johny Henricks in 2013.Earlier this year St-Pierre and the UFC struck a multi-fight contract and it was announced that he would be returning to challenge for the middleweight title against current division champ Michael Bisping.If St-Pierre is able to emerge victorious against Bisping he will join an exclusive club of champions to have held titles in different weight classes in the UFC. That club currently consists of only three men; Randy Couture, BJ Penn, and Conor McGregor.The fight between St-Pierre and Bisping has already been agreed to, and the UFC even held a press conference for the two men to promote the event. One odd thing about this fight, however, is that a date or venue has yet to be announced for it.St-Pierre must re-enter the United States Anti-Doping Agency (USADA) drug testing pool, which has put a halt on is return for the time being. While a date has yet to be announced for the bout, St-Pierre recently took to Twitter to hint at the possibility of the fight going down at one of the greatest sports venues of all time - Madison Square Garden.'Rush' took a selfie alongside Erik Owings at the New York Rangers game from MSG and teased that he 'could be fighting here in a few months':

The former 170-pound kingpin has not lost in MMA competition since 2007, going nearly a decade undefeated in the grueling sport. A return against a bigger man in Bisping should prove to be an interesting task for one of the greatest of all time.

Bisping is on the greatest stretch of his career, currently on a huge five-fight win streak. Those wins consist of a knockout victory over Luke Rockhold (whom he defeated to earn the 185-pound title), C.B. Dollaway, Thales Leites, Dan Henderson, and Anderson Silva.

'The Count' has already defeated one of the greatest of all time in Anderson Silva and is extremely confident that he can do it yet again when he steps into the cage opposite the Canadian. 

Who do you think will emerge victorious when Bisping and St-Pierre lock horns? And is it possible that they could meet up in New York at MSG?
