Lem's latest: Khan talks Martinez-Macklin, Pacquiao-Bradley

NEW YORK-- In December, Amir Khan lost his IBF and WBA junior welterweight belts to Lamont Peterson in the winner's hometown of Washington, D.C.

Khan (26-2, 18 knockouts) spent Tuesday and Thursday of this week in London and Washingon, D.C., respectively, promoting his rematch with Peterson (30-1-1, 15 KOs), which will take place on May 19 at the Mandalay Bay Hotel in Las Vegas -- and will be in Los Angeles on Monday doing the same.

Today, Khan attended the weigh-in for Saturday night's fight at Madison Square Garden between THE RING's No. 3-rated middleweight Mathew Macklin (28-3, 19 KOs), and RING champion Sergio Martinez (48-2-2, 27 KOs).

Martinez weighed 157.6 pounds compared to 158 for Macklin, who was last in the ring in June, when the Irishman lost a controversial split-decision to THE RING'S No. 2-rated contender Felix Sturm in the WBA beltholder's native Germany.

"I've known Matthew Macklin for about five or six years, so for me to be here is an honor, and I'm going to be supporting him 100 per cent. He should already be the world the champion, because that fight in Germany, that was his fight," said Khan.

For the undercard bout, super middleweights Don George (22-1-1, 19 KOs) and Edwin Rodriguez (20-0, 14 KOs) weighed in at 166 pounds each. For a clash of unbeaten heavyweights, Mogamed Abdusalamalov (13-0, 13 KOs), of Russia by way of Oxnard, Calif, weighed 221 compared to rival Jason Pettaway (11-0, 8 KOs), of Huntington, W.Va.

KHAN TO TRAIN WITH STABLEMATE MANNY PACQUIAO IN THE PHILIPPINES

Khan shares five-time Trainer of the Year Freddie Roach with WBO welterweight beltholder Manny Pacquiao, who defends his title against WBO junior welterweight titleholder Tim Bradley on June 9 at the MGM Grand in Las Vegas.

Khan said that he will leave early next month to train alongside Pacquiao in the Philippines.

"We'll train together for the first part of April," said Khan. "Manny's bought his own gym in Manilla, so they want us to train over there with him. I have to go and follow wherever Freddie goes."

Khan said he expects Pacquiao and himself to be joined by WBC middleweight beltholder Julio Cesar Chavez Jr. and former two-time titleholder Venezuelan-born Jorge Linares, who are also trained by Roach.

"Manny's his man first, and then, I'm second. Then it's Linares and then it's Chavez Jr.," said Khan. "So they have to follow him also, or if they don't want to follow, then they'll have to go their own way."

Khan said that he does not expect to spar with Pacquiao, as he has in past camps.

"The main camp, I'll running with Manny in the morning," said Khan. "But I don't think that we'll be sparring because we're facing different styles and opponents. But if he wants to spar, then we'll spar."
