George Groves accepts six figure bet from James DeGale

The winner takes all when James DeGale and George Groves fight on Saturday night at the O2 Arena. The pair clash for the British and Commonwealth super-middleweight titles.

And whoever emerges victorious will get the loser's purse after an extraordinary side bet at today's head to head press conference.

DeGale offered Groves the bet, which he duly accepted.

Frank Warren's purse bid for the fight was just short of £400,000, with DeGale taking the greater share as champion.

"The drinks are on me," said a jubiliant DeGale.

Chunk's trainer Jim McDonnell then offered his opposite number Adam Booth a £20,000 side bet which he too seemed to agree on.

"Groves is getting knocked out," said DeGale. "He's been knocked out in sparring and he's getting knocked out in the ring on Saturday."

But Groves hit back by saying: "I've had enough of DeGale's talking. Now it's time to shut him up once and for all."
