It has been said that good news travels fast.

Late last week, news broke that Ultimate Fighting Championship (UFC) would be faced with an "imminent" lawsuit from past and present fighters, one that is expected to accuse the world's largest mixed martial arts (MMA) promotion of violating antitrust laws.

Something former UFC lightweight champion Sean Sherk has experienced firsthand, according to his comments on Facebook:

"They have stuck it to too many people too many times. It's time to fight back! UFC has monopolized the entire MMA industry and they have used there monopolization to take away from the fighters 'myself included' and they've lined their own pocketbooks even more. Giving the fighters less in return and taking more."

And this new partnership appears to be the straw that broke the camel's back.

Sherk (36-4-1), 41, hasn't competed since a split-decision win over Evan Dunham back in late 2010. The retired "Muscle Shark" made his Octagon debut way back in 2001 and holds notable victories over Karo Parisyan, Nick Diaz, and Kenny Florian, among others.

If he does indeed have one last fight left in him, it may be reserved for the court room.
