Amir Khan’s promoter Frank Warren concluded negotiations with Marco Antonio Barrera’s promoter Don King at 4am Thursday morning. London is in the running to host the March 14th event, but Warren is still in negotiations, and may look for a site elsewhere in the UK. It was also confirmed that Nicky Cook will defend his WBO super-featherweight title on the undercard against mandatory challenger Roman Martinez, with Enzo Maccarinelli also in action against TBA. Warren said that ticket prices for the fight would be competitive, and he is expecting a sell out. Khan was installed as a slight favorite for the fight at around 11-8 with Barrera at even.
