Frank Warren defends this summer's Haye-Chisora fight

David Haye and Dereck Chisora will fight this summer after their brawl at a Munich press conference.

They will meet on 14 July at West Ham's Upton Park.

Despite Haye being retired and Chisora being stripped of his licence following their scuffle in February, the fight can go ahead after Chisora was licensed by the Luxembourg Board of Control.

BBC Radio 5 live Breakfast spoke to Chisora's manager Frank Warren.
