By Dan Ambrose: The 42-year-old Roy Jones Jr. really looked his age tonight in getting stopped by Russian Denis Lebedev in a brutal 10th round knockout in a fight that took place in Russia.

Jones spent the majority of the fight with his back against the ropes just covering up while Lebedev unloaded on him with powerful right hooks and straight left hands. Jones held out until the final seconds of the 10th when he was badly hurt by three straight right hands he took to the head.

Jones collapsed on the canvas after eating the third of three straight right hands. The fight was immediately halted with Jones out cold on the canvas and very, very hurt. If that loss doesn’t signal that it’s time for Jones to call it a career then I don’t what does. He needs to retire, period.

Also happening tonight is a fight between 46-year-old Bernard Hopkins and WBC light heavyweight champion Jean Pascal at the Bell Centre in Montreal, Canada. Hopkins wants to become the oldest fighter to ever win a world title, but he’s got beat mother nature before he can defeat Pascal.

Most fighters his age are sitting down watching television sporting a sizable gut. I don’t care that Hopkins is still fighting. He’s still old and when you get to that age the reflexes and the stamina can disappear overnight. Hopkins was able to get a 12 round draw with Pascal in his last fight last year in December, but that have been the last bit of brilliance we’re going to see of Hopkins. He may have lost any little bit of youth that he had left in his old body.

So, will we see Hopkins get destroyed or beaten up and get shown the door by Pascal tonight? Hopkins made mention of retiring if he loses. So we may see Hopkins going out the door, as well as possibly Jones – if he’s smart.
