Carl Froch's opponent for Saturday night's bill in Nottingham has changed once again.

Pole Albert Rybacki becomes the fourth figher who has at one time been scheduled to meet the unbeaten British super-middleweight.

Rybacki steps in after Rubin Williams pulled out on Thursday due to "personal problems", opting instead to stay in the US.

The Polish fighter is, like Froch, unbeaten so far in his professional career and has a record of 15 wins, with eight stoppages.

Froch said: "It's always difficult to fight an unbeaten fighter as he doesn't know how to lose and obviously he will put everything on line as he could gatecrash the world title, but I am in prime condition and looking forward to fighting on Saturday night."

Froch had initially been due to meet Russia's Denis Inkin in a final eliminator for the WBC title.

However, the Russian withdrew, as did his replacement Alejandro Berrio.

On the undercard, rising lightweight star John Murray will also have a different opponent.

He had been due to fight John Fewkes, but he has been diagnosed with gastroenteritis.

A new opponent has yet to be named.
