UFC Hall of Famer and former WWE Intercontinental Champion and NWA: TNA World Heavyweight Champion Ken Shamrock posted the following on his personal Facebook page:
I am not sure how to say this but I will try I have stepped back from fighting something I have done my whole I have never backed down from any fight & at time I have been verbally abused by fans because I have always stepped up to any challenge even when I was beyond my prime but I still stepped up against injuries & fighting my age but that's where I was at I did not make these fights I was asked to step up & fight to help the promotions & of course it was also the thing I loved most doing now I feel I am being pushed again by people calling me out & I hear some people say your to old you can't fight anymore but what you are asking me to do is to stop being me stick my head in the sand & let people punk me out you tell me how you do that after me never backing down from a challenge all of who tell me to hide maybe that's in your DNA but not mine I do not have plans to fight again but if I get pushed to far well then I have to be me AGAIN I HAVE NO PLANS ON FIGHTING AGAIN
Shamrock's last two MMA fights took place for the Bellator promotion. He suffered a knockout loss to the late Kimbo Slice in June of 2015 after nearly choking Slice out with a Rear Naked Choke. Shamrock then returned to the Bellator cage once again in February of 2016, taking on fellow UFC Hall of Famer Royce Gracie in their third match against each other. Gracie defeated Shamrock by knockout.
Wrestling fans may remember Ken Shamrock for his tenure with WWE in the late 1990s. He enjoyed considerable success in WWE, as he held the Intercontinental Championship, the World Tag Team Championship (along with the late WWE Hall of Famer The Big Boss Man), and also won the 1998 King of the Ring tournament. In 2002, Shamrock became the first World Heavyweight Champion in TNA/IMPACT Wrestling history, as he captured the historic NWA World Heavyweight Title at TNA's very first event.
