Tyson Fury says he could have knocked out Sefer Seferi within “10 seconds” but prolonged the bout as preparation for potential fights against fellow Britons David Price and Tony Bellew.
Albanian Seferi pulled out after four rounds of a controversial heavyweight bout at Manchester Arena on Saturday.
The men had spent the first two rounds of the non-title fight posturing.
“I could have knocked him out, but what would that have got me?” said former WBA, IBF and WBO world champion Fury.
The former world champion, 29, insisted he was “just getting into a rhythm” when the bout ended, and promoter Frank Warren also expressed frustration at his man not getting the chance to contest more rounds.
Warren said he will take Fury’s comeback slowly, with his next bout not until 18 August, but added that Liverpool fighter Bellew was “someone we would go for by the end of the year, no problem”.
Shortly after the fight, WBC world cruiserweight emeritus champion Bellew tweeted: “I will knock the big man Tyson Fury out. Simple as that.”
And Olympic and Commonwealth Games medallist Price – who was ringside for BBC Radio 5 live – said a fight between him Fury “would create a lot of interest”.
