Nate Marquardt is out of his fight with Rick Story, but UFC Live on Versus 4 still promises plenty of exciting fights on Sunday night at the Consol Energy Center in Pittsburgh, Pennsylvania.
Charlie Brenneman has stepped in to replace Marquardt, so welterweight contender Rick Story will still be competing on the card. Also, two heavyweight fights bolster the main card as Matt Mitrione looks to continue to success against Christian Morecraft and Cheick Kongo will go toe-to-toe with fellow kickboxer Pat Barry.
The card will also be stacked deep with one of the most intriguing preliminary cards of 2011. A few fighters competing on the wildly popular Facebook stream will be Tyson Griffin, Manny Gamburyan, Joe Stevenson, Joe Lauzon and Charles Oliveira.
Here are some predictions for fight of the night, submission of the night and knockout of the night.
