Anthony Joshua’s win over Wladimir Klitschko was his 19th by knockout in 19 professional bouts

A rematch between unified heavyweight champion Anthony Joshua and Wladimir Klitschko could take place at Cardiff’s Principality Stadium in October.

Briton Joshua stopped Klitschko at Wembley last month to add the WBA world heavyweight title to his IBF crown.

Wales’ rugby union team will play at the Principality Stadium for most Saturdays in November and December, but 28 October could be a potential date.

“Talks are ongoing over venues,” said Joshua’s promoter Eddie Hearn.

Joshua’s thrilling win over Ukrainian Klitschko was watched by a post-war record crowd of 90,000 at Wembley.

Staging a rematch outdoors could be difficult in the autumn, but the 74,500-capacity Principality Stadium’s retractable roof could make it a viable option.

Hearn has said he believes a rematch “will go ahead” –
