Yet another huge underdog walked away from a UFC match victorious Saturday, and paying off handsomely in the process.  Brazilian Gabriel Gonzaga knocked out Mirko (Cro Cop) Filipovic with a devastating kick to the head Saturday, administering the Croatian heavyweight a shocking taste of his own medicine at UFC 70: Worlds Collide.

For UFC bettors, this was an even bigger knockout depending on which fighter you laid money.

"Gonzaga paid out nearly $500 for every $100 bet at Bookmaker.com," said Sports911.com's Dan Shapiro.  Cro Cop was a huge -525 favorite.

UFC 69 featured another huge underdog walking off victorious with Matt Serra beating favorite UFC Welterweight champ George St. Pierre on the 7th. 

Serra's win paid out even more.  Every $100 bet paid $800 at Bookmaker.com (see website here).

With UFC 70, the 27-year-old Brazilian scored the mixed martial arts upset at 4:51 of the first round, after softening up and bloodying the heavily favoured Filipovic with some painful ground and pound before a soldout crowd of 14,921 at the MEN Arena.

Filipovic, known for his devastating kicks, found himself on his back 90 seconds into the round when he launched a kick and the Brazilian caught it, hurling him to the ground. Gonzaga hammered the 32-year-old Filipovic with elbows from above near the cage fence for some three minutes until referee Herb Dean surprisingly stood the fighters up.

The Brazilian (8-1) then laid out Filipovic (22-5) with the devastating right kick. Filipovic went done like a sack of bricks and took his time getting up. He eventually wobbled out of the arena having hardly thrown a punch on the night.

"Everybody has a plan - until they get hit," Filipovic said in a pre-fight promo.
