Anthony Joshua will defend his IBF and WBA heavyweight world titles against Kubrat Pulev at Cardiff's Principality Stadium on 28 October.
It will be Joshua’s first bout for six months, after the Briton beat Wladimir Klitschko at Wembley Stadium in April, to add the WBA title to the IBF belt he claimed in 2016.
The 27-year-old has a 100 per cent record, winning all of his 19 fights by KO so far.
Bulgaria’s Pulev is the mandatory challenger for Joshua's IBF title.
The 36-year-old has only lost once in his 26-fight career, when he was stopped by Klitschko in 2015. Since then he has won five fights in a row.
