The former World Extreme Cagefighting (WEC) lightweight champion -- who missed out on a title shot when Frankie Edgar and Gray Maynard fought to an unsatisfying draw early last year -- connected with a hellish head kick, which turned out Lauzon's lights almost immediately.
"Showtime" breaks it down:
"Right when I landed the kick I felt what part of this shin I hit him with, then I saw his eyes roll back, and I knew it was a done fight. To set it up, I came out in the southpaw stance and was just working the jab. I thought he was going to shoot sooner, so I kind of keep my range and stay far, but he was biting on the jab. I threw up the high kick and it was just his mistake."
Pettis goes on to explain that he has proven in his two last fights that he's worthy of being a contender. Prior to stopping Lauzon, Pettis battled Jeremy Stephens for three rounds to earn a split decision victory.
He hopes that his quick finish of "J-Lau" to kick-off the pay-per-view (PPV) card will push him over the edge.
"I felt this fight was somewhere close to a [number one title contender eliminator match]. He just beat Melvin Guillard, who was coming off a huge winning spree. And I finished him quickly -- I knew I had to finish this fight fast to get a title shot, so hopefully the UFC gives me my shot."
With top division contenders Jim Miller vs. Nate Diaz squaring off at the upcoming UFC on Fox 3 show, Pettis might have a little competition when it comes to determining the next in line to challenge newly-minted champion Ben Henderson.
However, he has what both of them do not, which is a recent win over "Smooth," as well as a "Showtime Kick" kicker.
