The score was tied before the fight was stopped, and Whittaker, the clear favorite in this fight, had serious problems in the ring. The 27-year-old "The Surgeon" has had four professional bouts in the past year.
Fraser Clark is expected to return to the ring as part of the same April evening. For the British heavyweight, it will be a comeback after last year's loss to Fabio Wardley. In that fight, Clark was stopped in the first round.
