British super-middleweight champion Carl Froch stretched his unbeaten run to 23 fights as he comfortably beat Albert Rybacki inside four rounds.
Froch's Polish opponent only took on the fight on Thursday following a succession of withdrawals and seemed content on soaking up the punishment.
The 30-year-old's timing, range of shots and power were clearly superior and he landed powerful shots at will.
The fight was stopped in the fourth to spare Rybacki further punishment.
606: DEBATE
Froch is the mandatory challenger for the WBC title but, with Joe Calzaghe certain to vacate, he could find himself in against former middleweight champion Jermain Taylor or the winner of the clash between Fulgencio Zuniga and Jean Pascal for the vacant crown.
He told BBC Radio Nottingham: "We want the Joe Calzaghe fight but we're going to have to wait and see about that one. He's looking for big-money fights, not genuine fights.
"I think it's 60-40 against. There's always a chance he'll want to defend his title against me. It's just whether he fancies one of those uppercuts on the end of the chin."
Promoter Mick Hennessey said: "Carl is the best super-middleweight on the planet. If Joe steps up and fights him, he'll find that one. He won't go the distance.
"Joe either steps up and fights him or steps down. If he steps down, Carl will fight for the WBC title. There's some big names in that division. Carl doesn't need Joe Calzaghe to be a superstar."
