Khan stays busy while waiting

Former junior welterweight titlist Amir Khan has been training for what he hopes will be a May 3 fight with pound-for-pound king and welterweight champ Floyd Mayweather Jr. But he has also been busy with some other things, including raising money for Typhoon Haiyan relief in the Philippines and getting ready to work as a television analyst.

Khan (28-3, 19 KOs), who turns 27 on Sunday, hosted a sold-out fundraising dinner for Islamic Relief's Typhoon Haiyan Appeal last Sunday in Bradford, England, that raised $136,000 through ticket sales and a charity auction at the black-tie event attended by more than 500 people.

Among the big-ticket items auctioned off were a Muhammad Ali signed boxing glove, a pair of Manny Pacquiao's trunks, a Usain Bolt running shoe and a meet-and-greet with Khan at his gym.

"When I heard about the devastation in the Philippines I wanted to do anything I could to help," Khan said. "The evening was an astounding success and the amount raised has exceeded all our expectations and I can't thank everyone enough for their generosity."

After the charity event, Khan headed for New York to get ready for his broadcasting duties on Showtime on Saturday night (8 p.m. ET) at the Barclays Center in Brooklyn.

Normally, Showtime's expert analyst is Paulie Malignaggi, but he's going to be a bit busy fighting fellow Brooklynite and former junior welterweight and welterweight titleholder Zab Judah in the main event. So Khan, who owns knockout wins against both Malignaggi (2010) and Judah (2011) in junior welterweight title fights, is filling in to call the quadrupleheader, which also features Devon Alexander in a welterweight title defense against Shawn Porter, interim junior middleweight titlist Erislandy Lara in a defense against former titlist Austin Trout and super middleweight titlist Sakio Bika defending against Anthony Dirrell.

"Having shared the ring with both men, I know together they will bring speed, power, ring craft and heart to the table," Khan said of Malignaggi and Judah. "Fighting in their own backyard, neither one of them will want to leave that ring the loser so it makes for an extremely intriguing matchup between two truly world class operators. The undercard is filled with some similarly great clashes, which could headline on their own."
