WWE News: Lawsuit reveals Lesnar locked out of wrestling until June 2010
Brock Lesnar's lawsuit against WWE claims that they are preventing him from working in his chosen field due to a no compete clause he signed last year shortly after WrestleMania. He decided he did not want to wrestle in WWE anymore because he didn't like the travel and wanted to pursue a dream of playing in the NFL.
He did make the preseason squad for the Minnesota Vikings, but ended up being cut before the season. He was not retained on the practice squad.
His no compete clause prevents him from working for any competitor, including other pro wrestling or professional fighting (i.e. UFC, Pride) organizations worldwide for the duration of the WWE contract he signed less than a year before asking for a release. That expiration date is June 30, 2010.
WWE's no compete clause includes the entire world, not just the U.S., because a competitor in Japan or any of the other countries WWE runs live events could use Lesnar to draw fans at a non-WWE event.
