The 21 year-old was due to battle cousin Tyson’s ex-opponent Firtha this weekend at the ESPRIT Arena in Dusseldorf until the American pulled out a few days ago.
Redzovic has been drafted in a late notice for Fury, but inadvertently looks a better test on paper for the undefeated heavyweight prospect.
The veteran, 38, has lost only once in 17 contests without heading anywhere near dangerous territory, but should be a mere stepping stone on Fury’s journey to bigger challenges.
In another addition to the Germany bill, Prizefighter champion Jono Carroll makes his third appearance of 2015 against an opponent yet to be named.
Carroll, 23, has won all eight of his bouts since entering the paid ranks in December 2012 and is highly regarded by many.
The super featherweight announced his delight at being part of such a massive bill that will be going out live on Sky Sports Box Office this Saturday night.
Fury and Carroll are so far the only two names taking up places on a sparse event, although more fights are expected to be confirmed by promoters K2 in the coming days.
