Las Vegas ? Just when it seemed Mike Tyson’s world couldn’t get more bizarre, he outdid himself.

A day after backing out of Saturday’s bout against Clifford Etienne, Tyson pronounced himself ready to fight Tuesday.

Now, though, Etienne says he doesn’t want to fight, leaving the former heavyweight champion in need of another opponent. Tyson’s mood swings are well known, but Etienne had a little fit of his own Tuesday.

“I’m going to show him I don’t have to live by Mike’s rules,” Etienne said.

“I think he has mental problems, but Mike has to live with that.”
