No less than an hour ago, Quinton "Rampage" Jackson announced on his personal website that he will retire from the sport of mixed martial arts in order to focus on his movie career.

The former UFC light heavyweight champion cites a perceived lack of respect from the UFC for the loyalty he showed the organization and Dana White in particular.

Jackson followed up his blog post with a Tweet inviting fans to read his announcement, "even the haters".

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 & controversial there is normally an instant replay. I can name a couple of instances. Instead they offered me the Vanderlei Silva fight which I gladly accepted even though I know it was a very risky fight for me to take because of all the drama that was happening to me at the time. I fought that fight with a jaw injury and then a couple weeks later Dana called me and asked me to fight Rashad. For the first time I said no, I didn't want to fight because it was such short notice & I wouldn't have had a long break between camp. Dana talked me into fighting Rashad anyway but Rashad refused the fight and so I had to fight Jardine as a favor to the UFC instead of getting my belt back (which wasn't even worth it to me financially).

Then I reinjured my jaw in the fight with Vanderlei & Jardine. Frank Mir gets hurt so they wanted to switch my fight from UFC 100 to the fight Frank couldn't make it to but I couldn't fight cause I needed jaw surgury. So they give Machida the fight against Rashad & they told me they want me to coach TUF season 10 against Rashad. That's why I wanted Rashad to win so bad but when Rashad got knocked out I told them I wanted to fight Machida for the belt but Dana told me if I coach TUF against Rashad that I could fight Machida afterwards cause this was a different type of ultimate fighter show they were doing. After I signed the contract Dana then changes his mind & says I have to fight Rashad & even told me what to...
