LONDON: Dominican Republic light-heavyweight Lenin Castillo was taken to hospital after a brutal second-round knockdown by Briton Callum Smith at the Tottenham Hotspur Stadium on Saturday (Sep 25).
The international light-heavyweight contest, ended suddenly as Castillo hit the canvas after a powerful punch to the head.
Castillo received immediate attention from several medical staff in the ring, before being taken away on a stretcher.
Fight promoter Eddie Hearn took to Twitter to say that Castillo was "responsive and on his way to hospital".
This fight was the 31-year-old Smith's first at light-heavyweight, having suffered the inaugural defeat of his professional career in December last year when Saul 'Canelo' Alvarez convincingly deprived him of his World Boxing Association (WBA) super-middleweight title.
The bout was on the undercard for the world heavyweight showdown between Britain's IBF, WBA, WBO and IBO champion Anthony Joshua and Ukraine's Oleksandr Usyk.
