It looks like Quinton "Rampage" Jackson may be finished fighting. This posting came from his website last night:
The UFC has done a lot for me but I think I have done more for them. The UFC bought WFA to get my contract & they saved my life, so I felt loyal to them. They pushed me into a fight with Chuck Liddel even when I clearly stated I wasn't ready to fight for the belt because the American fans didn't know me but I took the fight and didn't complain & after I won the American fans booed me for the first time which changed the way I saw them & it hurt me deeply.
Then before I can even get out of the cage they announced that I was fighting Dan Henderson without even asking me. After I beat Dan Henderson, I made history in becoming the first undisputed champion in MMA but was never even given the pride belt in the cage & I was never promoted as the undisputed champ. Later Anderson Silva was.
Then they had me coach TUF season 7 and fight Forrest and the fight was very controversial & normally when a fight is that close ...
