"King Mo" Lawal's retirement fight did not go according to plan after he suffered a first-round knockout loss to Andrew Kapel.
The former Strikeforce light heavyweight champion lost to a vicious knockout in just 82 seconds to the unheralded Kapel.
"Yeah man, it's my last fight. I had a great time fighting. It is what it is," Lawal said. "I had the opportunity to do a thing that Kapel did to me, I did to Travis Wiuff. Now it's time to give back, he got that on me."
