As far as I know Froch - Abraham is only postponed not cancelled, they'll probably try and make both these fights happen on the same night now
They were recently spotted in Paris and Dirrell was on one knee, singing "Wonderful Tonight" by Eric Clapton.
Froch Abraham is supposed to be happening late Nov, maybe in December. I think once that is confirmed then Ward and Dirrell will be set. I hope the next round happens this year, would be awful if the super 6 fell apart.
