It was beyond shocking. You know when you watch something unfold before your eyes that's not supposed to happen, and for that brief moment you can't comprehend what you just saw? For a split second, your brain short-circuits, confusion sets in, and nothing makes any sense?

Well it happened Saturday night in Las Vegas, when Antonio Tarver landed a perfect left hook to the chin of Roy Jones Jr. and sent him falling to the canvas. Jones fell into the ropes and tried in vain to get back on his feet. It was Jones's heart, the heart of a champion, that allowed him to somehow rise to his feet and beat the count, but he was done, and referee Jay Nady waved off the fight and signalled the biggest upset in boxing history since Buster Douglas knocked out Mike Tyson in Tokyo.

The suspense going into the rematch reached the boiling point just seconds before the opening round. When Nady brought the two fighters to the centre of the ring to give them their instructions, he asked, "Any questions?", to which Tarver quipped, "Yeah, I got a question: Any excuses tonight, Roy?" (referring to the fact that much had been made about Jones's inability to make weight properly in their first fight). The crowd loved it, and the stage was set.

In round 1, both fighters were tentative, but Jones stalked around the ring and was the busier of the two. Tarver looked unsure of himself, as he did in their first fight when Jones turned up the heat. Then in round 2, Tarver crouched down from a lazy jab from Jones and came out of the crouch with a left hook over Jones's right. It landed flush and sent Jones reeling back.

The crowd erupted like nothing you'd ever seen, shocked and fascinated at the sight of the invincible, seemingly immortal Roy Jones being knocked down. If Roy Jones is Superman, then Antonio Tarver held a handful of Kryptonite.

After the fight, Tarver, high on victory and redemption, yelled to the judges,"Judge THAT! Judge THAT!" He had bullied Roy Jones and proved his claim as THE best light heavyweight in the world. Jones, when interviewed by Larry Merchant, hinted at retirement, or fighting heavyweights again. He said that "everyone wants to fight Roy Jones, but Roy Jones don't wanna fight everybody", meaning that he's finding it increasingly difficult to get motivated for fights like these.

If that's the case, then maybe you should get out of the game, Roy. Like you told Merchant, you have nothing left to prove, so why give half-hearted efforts in the ring? Your legacy is secure. You have more money than you know what to do with. Why not leave now?

Roy Jones Jr. will be back. His ego and sense of self-importance will drive him back into the ring in pursuit of redemption, revenge, or renewed greatness. Once the shock of getting dropped subsides, Roy will readjust his game and come back with all guns blazing. At 37, he's not a young fighter, but he certainly didn't look shot last night, either.

But only Roy Jones knows what he plans on doing next.
