Top 5: Fastest UFC welterweight knockouts

Duane Ludwig vs. Jonathan Goulet

UFC Fight Night 3
Jan. 16, 2006 | Las Vegas
Goulet paid for his miscalculations at the Hard Rock Hotel and Casino, where 1,008 fans were on hand to witness a historical nugget. The Canadian marched toward Ludwig, a vastly superior kickboxer, and walked into a right cross that dropped him face first on the canvas in the first round of their welterweight affair. After a brief pause, referee Mario Yamasaki signaled the stoppage and sent Ludwig back to a jubilant corner that included longtime mentor and former UFC heavyweight champion Bas Rutten. The UFC recognizes it as the second-fastest knockout in its history at six seconds, though the official time of the stoppage remains unchanged at 11 seconds on the Nevada Athletic Commission books.

Johny Hendricks vs. Jon Fitch

UFC 141
Dec. 30, 2011 | Las Vegas
A picture-perfect left hook from Hendricks laid waste to the former welterweight title contender in their welterweight feature at the MGM Grand Garden Arena. It was over just 12 seconds after it began. Fitch—who had not been finished in more than nine years and had lost only once in his previous 23 appearances—threw a straight right hand, backed away and ate the punch that ended his night. The left hook found its mark, and Fitch collapsed. Hendricks moved in and fired off one more left hand for good measure, as referee Steve Mazzagatti stepped in to prevent the American Kickboxing Academy mainstay from absorbing further punishment.

Anthony Johnson vs. Chad Reiner

UFC Fight Night 10
June 12, 2007 | Hollywood, Florida
Johnson introduced himself to the masses in a dynamite organizational debut at the Seminole Hard Rock Hotel and Casino, where he wrecked the Premier Combat Center product in the first round of their welterweight encounter. Reiner packed his bags 13 seconds into Round 1. He plowed forward behind wild winging punches, only to be met by a sweeping left hook from the powerful Johnson. The blow stunned Reiner and left him virtually defenseless on the feet. Johnson then proceeded to connect with another crushing left that brought their confrontation to an emphatic close.
