Jackson lost to Evans in just three rounds and he blames his lacklustre performance on film work as the new B.A. Baracus.
He tells TV show Extra, "This fight was, like, so much pressure. I never had this much pressure because the movie was coming out. I really wanted to beat him.
"I almost lost my career just for this movie. It was weird I was going through the same thing B.A. was going through, where I didn't want to fight no more."
