Jon Jones left stunned by Gable Steveson's shocking UFC 331 knockout loss in candid cageside footage - Yahoo Sports

Jon Jones was left just as stunned as everyone else by Gable Steveson's shocking loss at UFC 331 .

An Olympic champion who entered UFC 331 as one of the most ballyhooed heavyweight prospects in MMA history, Steveson suffered the first defeat of his pro career Saturday night at Crypto.com Arena in Los Angeles, falling to Sean Sharaf by knockout just 12 seconds into their heavyweight bout. Sharaf connected with a picture-perfect left hand that sent Steveson tumbling to the canvas before the fight ever really began.

Steveson was listed as high as a -1800 favorite heading into the bout, making Sharaf's shocking knockout the biggest UFC betting upset of all time at Draft Kings.

Jones, who has worked closely with Steveson throughout his transition to MMA, was in his corner for Saturday's fight alongside coaches Greg Jackson and Brandon Gibson.
