Amir Khan-Lamont Peterson bout in D.C.

Unified junior welterweight titleholder Amir Khan is taking the bold step of making his next defense in Washington, D.C. -- the hometown of Lamont Peterson, his opponent on Dec. 10.

"Khan-Peterson definitely will be in Washington, D.C.," Golden Boy promoter Richard Schaefer told ESPN.com on Thursday. "We are still looking to see which venue, but it will be in Washington."

Schaefer said that Seth Mitchell (23-0-1, 17 KOs), the top American heavyweight prospect, who is from the Washington suburb of Brandywine, Md., will fight on the HBO-televised undercard against an opponent to be determined.

Schaefer said he's looking at various venues in the nation's capital but hopes to have the card take place at the Verizon Center, the city's major arena, which is home to the NHL's Capitals, NBA's Wizards and Georgetown's men's basketball team. The Hoyas have a home game scheduled for Dec. 10, but it is possible a deal could be struck to change it.

"With a big fight like Khan-Peterson, and with Peterson being from Washington, and Seth Mitchell being on the card along with some other local talent, Washington is the place for this fight," Schaefer said.

England's Khan (26-1, 18 KOs) recently visited the city and enjoyed himself as a guest at a dinner honoring Muslim athletes hosted by Secretary of State Hillary Clinton.

Khan will be making his sixth title defense, including a fifth-round knockout of Zab Judah to unify belts on July 23 in Las Vegas.

Peterson (29-1-1, 15 KOs), the mandatory challenger, will be getting his second shot at a world title. He lost a decision to Timothy Bradley in 2009. There will be a media tour next week to promote the fight, beginning with a stop in London on Tuesday followed a visit to Washington later in the week.
