According to Adam Swift from mmapayout.com and sherdog contributor, Randy Couture has a contract with Mark Cuban's HDNET Fights. Here is the meat of the article.
"New details of the action have been revealed in the complaint obtained by Sherdog.com. According to the filing, HDNet Fights has entered into a contract with Couture that is scheduled to commence upon the expiration of his Zuffa promotional agreement. At that time, the company plans to promote a fight between Couture and Fedor Emelianenko in Dallas, assuming terms can be reached with the highly regarded Russian heavyweight.
The existence of an actual contract between HDNet Fights and Couture is believed to be key to the company's action in Texas. Without it, it is unlikely that the court would find an actual controversy ripe for adjudication.
According to the filing, Couture has stated that he believes his Zuffa promotional contract expires with the stated term of the agreement in July, while Zuffa maintains that the contract remains valid indefinitely under the infamous "retirement clause." In the complaint, HDNet Fights characterized Zuffa's contention as "outrageous."
"Zuffa's position regarding Couture is both illegal and involves critical timing," the filing states. "First, like all fighters, Couture's ability to fight at a championship level will diminish as he ages. Through their actions, Zuffa seeks to ensure that Couture is prevented from gainful employment and practicing his craft until he cannot be an elite fighter. Importantly, the law in Texas is clear that indefinite employment restrictions such as Zuffa claims to be enforcing are per se illegal and against public policy."
