Lesnar had previously signed a no-compete clause in order to be released from his contract with WWE, which prohibited him from working for any other sports entertainment or mixed martial arts companies before June 2010. Lesnar had anticipated leaving wrestling entirely, but his inability to secure a career in professional football led to him challenging this ruling in court. WWE responded by demanding damages as a result of Lesnar allegedly breaching the agreement by appearing at a New Japan Pro Wrestling show in 2004. In July 2005, the two sides dropped their claims and entered negotiations to renew their relationship. WWE had offered Lesnar a contract, but on August 2, 2005, WWE's official website reported that Lesnar had withdrawn from any involvement with the company. The lawsuit was then entered into settlement on September 21, but talks broke down.
A 6 year no compete clause?
Sounds a bit extreme to me, anyone have any idea why they did this?
