MEMPHIS -- On Mike Tyson's list of lessons learned from his 49-second domination of Clifford Etienne, a few stand out:
First, rhinos don't dance, but they do hit the canvas with a thud.
Second, one powerful right hand does not mean Tyson has any chance in a rematch with Lennox Lewis.
"I'm not going to lie to myself and lie to the public," Tyson said. "I need more fights. I'm not interested in getting beat up again."
Tyson rambled on as only he can after Saturday night's fight, touching on everything from his bad back (broken, he says) to his desire to party (it's big) to his future in the ring (more Etiennes).
Etienne -- also known as the Black Rhino -- had gone down seven times in one fight with soft-hitting Fres Oquendo two years ago. Tyson, 36, proved the last thing to go in an aging heavyweight is his punch when his right hand flattened Etienne.
Etienne tried to punch with a puncher, and as soon as Tyson landed his right, he walked away knowing it was over.
"That's what rhinos do," Tyson said. "Rhinos don't dance."
The 15,171 at the Pyramid went wild over the sixth-fastest knockout of Tyson's career. But Tyson was more realistic about what it all meant.
"People are excited to see me knock guys out because that's how I made my reputation," he said. "But I need more rounds. After a fight like this, 49 seconds, I can't go in there against Lewis, a confident fighter who's accurate. I need to go back to the gym."
Tyson claimed after the fight that doctors told him he had a broken back from a 1997 motorcycle accident. His doctor said the injury was uncomfortable but nothing serious enough to keep him from fighting.

James will sit out as part of a two-game suspension ordered by a judge, who reinstated the 18-year-old after a state commission ruled him ineligible for accepting two free retro jerseys from a Cleveland clothing store.
