Georges St-Pierre has returned to Tristar Gym in Montreal to resume training.
The former UFC welterweight champion was cleared by doctors after getting surgery on his ACL in April, according to Bleacher Report. Tearing his ACL prevented him from training for six months.
The Montreal native hasn't fought in the UFC since beating Johny Hendricks at UFC 167 last November, stating shortly afterwards that he would like to take time away from MMA for personal reasons. He would go on an indefinite hiatus from the UFC after handing over the welterweight title.
GSP's receiving of medical clearance for his left knee was confirmed by UFC President Dana White, Mirror.co.uk reported.
"They cleared GSP's knee. After surgery like that it still takes about another 30 days before you start to mentally feel right. But he's in a good spot," White said in an interview with UFC.com.
While discussions about a return to the UFC have yet to take place, White believes there is a good chance that GSP will come back.
"His knee just got cleared and he'll start training again and getting back into shape," White said. "He'll let us know when he's ready."
St-Pierre recently said that he will only come back if he and his opponent are tested thoroughly for performance-enhancing drugs, Bleacher Report said. He previous said that the use of these drugs in MMA was one of the reason for his hiatus.
There is currently no definite answer as to whether GSP will return to the Octagon or leave MMA for good. However, his return to training is raising the hopes of fans who want to see him fight again.
