Froch: "Joshua is done."

"I don't want to say this is the end for A.J., that he'll never fight again. But I don't see a way back for him.

I wish Joshua was in the right position and strong enough, both physically and mentally, to say, 'OK, I'm going to fight Tyson Fury.' But I just don't believe that. Not after the beating he took in the Dubois fight. I think he's done," Froch said.

Recall that in September, Dubois knocked out Joshua in the fifth round in the main event of the evening of boxing at London's Wembley Stadium.
