Callum Smith says he will now have to assess his future in boxing after his stoppage defeat to Arthur Beterbiev.
Beterbiev defended his WBC, IBF and WBO light-heavyweight titles in Quebec on Saturday night, dropping the Briton twice in the seventh round with a series of crushing shots.
The win sees the 39-year-old maintain his remarkable 100 per cent knockout streak in boxing, having stopped all 20 of his opponents to date with Smith the latest to join that list.
The prospect of a mouth-watering undisputed title showdown with WBA champion Dmitry Bivol now looms large with expectation the two will meet with all four world titles on the line later in the year.
