The fight had just begun... 17 seconds in, Weidman delivered a leg kick which Hall checked, and you literally see his leg snap. It takes a second for it to register, and Weidman then collapses in pain as he tumbles to the mat.
Hall won by TKO, in front of a packed crowd at the VyStar Veterans Memorial Arena in Jacksonville. Weidman was taken out on a stretcher.
After the fight, Hall said, "I've got nothing but respect for Chris Weidman ... He's truly one of the best. It's a crazy story, that he was the first man I fought that defeated me [in 2010], that introduced me to fear.
