Chisora, 29, was due originally to face belt holder Kubrat Pulev, although the Bulgarian vacated the blue strap to concentrate solely on defeating Tony Thompson in an IBF eliminator – which he accomplished last week.
Denis Boytsov was then put forward by the EBU as mandatory to compete with Chisora for the newly-vacated title, although an agreement was not forthcoming and Gerber has now stepped in as a replacement.
The fight will take place on home soil for Chisora at the Copper Box Arena as ‘Del Boy’ looks to build on his recent win over undefeated American Malik Scott which ended a poor run of results for the Finchley fighter.
25 year-old Gerber comes into the clash with Chisora with questionable credentials after losing to another Briton in Michael Sprott at the back end of last year and only holds an eight-round win over journeyman Gbenga Oloukun since then.
The 6ft 3ins Kazakhstan-born puncher, who holds a 24-1 C.V with 14 stoppages, has fought solely around central Europe since turning pro in 2007 and is largely untested at Chisora’s level, which should see the ex-British champion head into the fight as favourite.
