According to $kala this is a one-fight cooperation between Affliction and EliteXC, but it's admittedly a doosy:

At least two fighters will not sit on the sidelines following the postponement of Affliction’s Oct. 4 "Day of Reckoning" event in Las Vegas.

Former UFC champion Andrei Arlovski (13-5) and IFL kingpin Roy Nelson (13-2) have been offered a heavyweight bout at EliteXC "Heat" Oct. 4 at the BankAtlantic Center in Sunrise, Fla. The event will be aired live on CBS.

Arlovski’s management team would not comment Wednesday on the proposed bout, while Nelson’s attorney, Rod Donohoo, also refrained from remarks. However, Sherdog.com has learned from separate sources that both fighters have agreed in principle to the match and that contracts have been issued for review.

A few things:

1. This is a significant improvement of the EliteXC card. Nelson isn't the creme de la creme of the heavyweight division, but this is a legitimate heavyweight fight. To think, though, that Kimbo Slice vs. Ken Shamrock is the main event is hard to swallow. But this fight added to the Shields vs. Daley bout creates a rock solid line-up with a legitimately popular Arlovski fighting on primetime network television. Well done, EliteXC.

2. Let's be clear: this is a Hail Mary pass, but it's a damn good one. The Arlovski addition - in exchange for lifting the Affliction ban - is quite a deal. It's no long term solution, but it's enough to buy them some time.

3. I distinctly recall Gary Shaw in several interviews joking about Affliction's MMA efforts and they they couldn't compete. My how desperation changes priorities.

4. Competition is a wonderful thing, but it works two ways. Expect Dana White to see EliteXC's raise...and then some.
