Carl Froch has retained his WBA and IBF super-middleweight titles with a controversial ninth-round stoppage of George Groves in Manchester.
Froch was floored by a flinging right hand in the opening moments but clawed his way back into the bout and won a spectacular duel when referee Howard Foster jumped in to end the contest in the ninth.
Foster's intervention with Groves still on his feet sparked uproar, with both corner teams briefly squaring off in the ring while a crowd which had started off resolutely pro-Froch roundly cheered the challenger.
