Scheduled for 10 rounds, Helenius vs Sprott will be on the undercard of the WBO super middleweight title rematch between champion Arthur Abraham and former belt-holder Robert Stieglitz.
The 6'6½"/200cm 'Nordic Nightmare' from Finland won the vacant European Heavyweight title via a hotly disputed split decision over Dereck Chisora (then 15-1, 9 KO) in December 2011 but was forced to take 11 months off due to a serious shoulder injury following that bout.
In his most recent bout, last November, Helenius loooked sluggish in defeating rugged journeyman Sherman "Tank" Williams via a unanimous decision and was even rocked in the sixth by a big overhand right.
The 38 year old Sprott is coming off an upset win of sorts in December after handing Edmund Gerber his first loss. The verdict was a majority decision.
Sprott (37-19, 17 KO) is ranked No. 30 in the heavyweight division by BoxRec and Robert Helenius (18-0, 11 KO) is No. 10 by the same publication.
Arreola vs Stiverne
Originally scheduled for Saturday, this battle of top heavyweight contenders will take place on April 27 at a site to be announced. Arreola pulled out of their March 9 showdown citing bronchitis.
Arreola, 31, has KO'd 30 of his 35 victims, while the 34 year old Stiverne has stopped 20 of his 22 conquests inside the distance.
An injury earlier this year limited Arreola's activity in 2012 to one fight – a first round KO of Eric Molina in February. Stiverne matched Arreola's 2012 bouts posting a win (via unanimous decision) against Willie Herring in April.
