Wilkinson has been released from his exclusive deal with the promotion. Wilkinson fought for the promotion three times, going 2-1. Wilkinson has also previously fought in the UFC, losing to Cody McKenzie at The Ultimate Fighter 12 Finale.
Wilkinson's contract with Cage Warriors is still valid for several more months until January 2014, but they are currently unable to book him in a fight in that time frame. As such, Wilkinson is now allowed to pursue other options.
Cage Warriors CEO Graham Boylan said on the announcement, "Aaron is contractually committed to Cage Warriors until January 2014, but we don't have any plans for him to compete between now and then. We don't intend to offer Aaron a new deal so it makes sense for us both to part company sooner rather than later. I wish Aaron the very best with his career, which I'm sure will be a success on the back of a big win last weekend."
Boylan added: "We've got four more big shows scheduled between now and the end of the year but all cards are already stacked, so unfortunately there's no room for Aaron to fight once more before his contract expires."
Cage Warriors is holding their next event, Cage Warriors Fight Night 9, on October 25 in Amman, Jordan.
