Recently, Tristar Gym head coach Firas Zahabi revealed one of his unorthodox training methods with Georges St-Pierre. One of them was encouraging training partners to knock out or put the two-division UFC champion on his back, in exchange for $5,000.
Apparently, one of those training partners did drop St-Pierre pretty badly during training, but the wager was not on the table at the time. However, it did leave GSP with a concussion two weeks out from his UFC 111 title defense against Dan Hardy in 2010.
During the most recent episode of the JRE MMA Show, Zahabi recounted that moment during training when he admitted that he was close to ending that particular sparring session.
