MIAMI -- Roy Jones Jr.'s punch came out of nowhere and stunned challenger Glen Kelly.

	Glen Kelly gave it his best shot, but Roy Jones was simply too much.

Backed against the ropes in the seventh round, Jones put both hands behind his back, faked with both his shoulders and unleashed a lightning-quick right that sent Kelly to the canvas and Jones to victory Saturday night.

"It's hard to explain stuff like that," said Jones, chuckling. "When you're a born fighter, you're just a born fighter. There's all kind of stuff I got here that never comes out because I don't ever hardly need it."

Jones, 46-1 with 37 knockouts, required minimum effort to successfully defend his WBC, WBA and IBF titles in the 175-pound division.

Jones floored Kelly (28-1-1) with 2:17 elapsed in the third with a left uppercut that snapped back the challenger's head.

He dropped Kelly again in the sixth round with a vicious left to the body that left Kelly gasping for air. Jones landed two other crushing body shots in the round.

Kelly, who seemed to be retreating throughout the fight, said before the bout that his only chance was to pound Jones and get inside to neutralize his speed.

But Jones kept his distance and was able to use his speed to measure his shots. He connected on 53 percent of his power shots, while Kelly landed 20 percent.

Kelly said he didn't even see the punch that floored him at 1:55 of the seventh round.

"He's tricky," Kelly said. "I've got no excuse. He's just too good."

Jones, an inch shorter than Kelly, weighed in at 172 pounds. Kelly weighed 174½.

Jones stunned Kelly several times in the second round. He got to the challenger with a quick right-left combination to the head, and seconds later buckled Kelly's knees with a roundhouse right and two quick lefts to the head.

Kelly was another in a line of average opponents for Jones, who has rarely been challenged since turning pro after the 1988 Olympics. Kelly, who is of half-Australian Aborigine heritage and works full-time as a garbage collector in Sydney's suburbs, was fighting his third bout in the United States.

Jones, who recently released a rap CD and performed three of his songs last week at a South Beach nightclub, brushed off comments by Kelly that the champion might have been distracted with his activities outside the ring.

"I did two videos last week and performed last week, and still kept my mind focused to make sure I was ready," Jones said.

The fight was the second half of an HBO television doubleheader. In the opening fight in Reading, Pa., Bernard Hopkins defended his undisputed middleweight title by stopping Carl Daniels in the 10th round.

Hopkins, who upset Felix Trinidad in October to win the titles, could be on the horizon for Jones. They would have to meet somewhere between 160 pounds and 175 pounds. Jones has demanded more money than Hopkins, while Hopkins wants the money split evenly.

Jones beat Hopkins in 1993 for the then-vacant IBF middleweight title.

Jones, whose promotion company, Square Ring Inc., put together the fight, made $1.5 million, while Kelly made $512,000.

About 8,000 people attended the fight, the biggest in Miami since Felix Trinidad defeated Mamadou Thiam in July 2000. Sitting near each other at ringside were O.J. Simpson, attorney Johnnie Cochran, baseball players Barry Bonds and Gary Sheffield, and Miami Dolphins players Zach Thomas and Jason Taylor.

Undercard: Wright retains his junior middleweight title
Ronald "Winky" Wright stopped challenger Jason Papillion in the fifth round to keep his IBF junior middleweight championship.

Wright (43-3, 25 knockouts) opened a cut over the right eye of Papillion (34-7-1) by the second round.

In the fifth, Wright, of Tampa, followed a devastating right-left combination to Papillion's head by landing six straight punches before the fight was stopped with 2:44 elapsed in the round.

"When I threw the one-two, he froze," Wright said. "I went after him since I knew I had him."

Papillion, of Broussard, La., landed just 17 percent of his punches and allowed Wright to dictate the pace of the bout.

Wright is a protege of Roy Jones Jr., who beat Glen Kelly in the card's main event.

Also on the undercard, Clifford Etienne, 23-1 with 17 knockouts, stopped Gabe Brown (11-2) at 2:57 of the seventh round in a heavyweight match.
