Watch out pedestrians -- Quinton "Rampage" Jackson was just released into the wild.

After being refused from a Orange County jail for being "medically unfit" -- Rampage was treated an O.C. hospital and released on $25,000 bail.

We're told UFC president Dana White posted the bail. What a nice boss!

Also, the following was just posted on TMZ.com:

When the Toyo tire company decided to officially sponsor Rampage Jackson and plaster their name on the side of his monster truck, there's no way in hell they could've expected this kind of exposure in return. Now, the company, who's name was clearly displayed on Rampage's mayhem-causing, fear-inducing billboard on wheels has made it clear they have no intentions of dropping the fighter -- even though he managed to blow out one of their tires during the police chase yesterday. Any publicity is good publicity, right?
