Sergey Kovalev stopped Ismayl Sillakh 52 seconds into the second round to retain his WBO light heavyweight title on the Adonis Stevenson-Tony Bellew card Saturday in Quebec City, Canada.
Kovalev (23-0-1, 21 knockouts) put Sillakh (21-2, 17 KOs) down with a right to side of the head about 30 seconds into Round 2, hurting him badly. Sillakh got up on shaky legs but went down again from a right-left combination, which left him unable to continue.
Kovalev now has seven consecutive knockouts, six within four rounds. Sillakh, a one-time amateur star from Ukraine, had bounced back from a knockout loss to Denis Grachev last year to win four in a row.
A full report will follow shortly.
