The second-guessing regarding last night’s decision to substitute Seth Petruzelli in place of a medically disqualified Ken Shamrock in the main event of EliteXC and CBS’ “Saturday Night Fights” has already begun.

Welterweight Luke Cummo has been forced to pull out of a planned Dec. 10 bout vs. Steve Bruno during UFC Fight Night 16: “UFC Fights for the Troops” in Fayetteville, North Carolina due to injury.

You could say it’s never happened in MMA but it did earlier this decade just prior to a UFCpay-per-view event in Atlantic City when Kevin Randleman tripped on a pipe just moments before having been scheduled to fight.

EliteXC’s latest installment of CBS Saturday Night Fights, EliteXC “Heat,” has now come and gone and it’s time for us to hash through what we saw this evening. For the most part I thought the show was very entertaining. It contained striking battles, knockouts, some grappling, a submission, and one hell of a surprise. Let’s break it down, shall we?

Seth Petruzelli shocked the world Saturday night at EliteXC: Heat on CBS when he KO'd Kevin "Kimbo Slice" Ferguson at the start of the first round after a barrage of punches.

A co-headlining bout on Nov. 8 between Nick Diaz and Eddie Alvarez for the vacant EliteXC title will be announced during tonights’ CBS’ telecast of Saturday Night Fights.

Ken Shamrock not fighting Kimbo Slice in Elite XC due to injury.

Ricardo Almeida has pulled out of UFC 90 due to an “undisclosed injury.” Almeida was set to face off against Matt Horwich in a middleweight matchup on the undercard of the pay-per-view. Now highly touted middleweight prospect and Renzo Gracie student Dan Miller will step in to face Horwich in Almeida’s place.

In an attempt to pull the ripcord on their financial free fall, EliteXC made a deal with the sponsorship-devil and allowed Affliction to again promote their clothing as well as their fighters under the Elite XC banner. Andrei Arlovski vs. Roy Nelson is the first attempt at a joint product, as both fighters are under the Affliction promotional contract. This adds hardcore credibility to a show that was stacked heavily towards mainstream attractiveness.
