George Groves set for 'most important fight' of career

British super-middleweight George Groves has admitted that he faces the biggest fight of his life this weekend when he takes on Christopher Rebrasse.

The 26-year-old was knocked out by Carl Froch in May to miss out on the WBA and IBF world super-middleweight titles, but he insists that Saturday's WBC eliminator at Wembley Arena is an even bigger occasion.

"This is more important than any other fight I've had," Groves told BBC Sport. "I lost my last fight and if I lose this one there will be some serious things that need addressing."

The WBC title is currently held by American Anthony Dirrell.
