According to MMA Weekly, Affliction will use the unified MMA rules. This ruling of course will allow the fighters to use elbows on the ground, which has been the most glaring difference between many of the U.S. fight promotions. While organizations such as the Ultimate Fighting Championship and EliteXC have always allowed elbows under the unified rules, other promotions such as the International Fight League and Strikeforce have taken away elbows as a legal maneuver.
