Usyk to face 38-year-old Witherspoon

Oleksandr Usyk will fight 38-year-old Chazz Witherspoon in his first fight at heavyweight on Saturday after original opponent Tyrone Spong returned an adverse doping test.
Usyk, 32, has not fought since he defended all four world cruiserweight titles against Tony Bellew last year.
Witherspoon is 74th on Boxrec’s heavyweight ratings – four places below Spong – with a record of 38 wins and three losses.
Spong, 34, spent much of his combat career in mixed martial arts and also competed in kickboxing before winning his first 14 fights as a boxer.
