CHRIS EUBANK Jr will top the bill next Saturday at Sheffield Arena after headliner Kell Brook was forced out of his IBF world welterweight title clash with Diego Chaves by injury.

Brighton fighter Eubank Jr, 26, defends his WBA Interim world middleweight title against American Tony Jeter.

Brook was set to make the third defence of his belt against the dangerous Argentine, but having spent time in hospital with the injury and taking the advice of medical experts following scans, the Sheffield star will now look to face Chaves later in the year.

Promoter Eddie Hearn said: “Kell picked up a rib injury in sparring yesterday and spent most of the day at hospital yesterday.

"Kell was desperate to fight but it was simply impossible and we will now look to reschedule the bout for the end of the year.”

It will be Eubank Jr's first defence of the title he won in February this year when he stopped Russian Dmitry Chudinov.
