I ferreted out the quotes from Dan Rafael's chat, and they aren't as promising as the OP indicated:

The Ward camp telling you they want GGG this fall is HUGE!! Can we expect a story soon? Will you get a reaction from Loefler?

He's been saying that. Their issue, besides money and split, is weight.

Better fights Ward kovalev or ward ggg

I'd be thrilled with either. The Ward camp told me today their preference is to make GGG for this fall and then go after Kovalev, which makes sense. Ward isn't going to go to light heavyweight and then come back down to face GGG. So face GGG now at whatever weight they can agree on and then, if all goes well, move to 175. Ward can go from an afterthought having fought one nothing fight in 19 months to a huge deal quickly if he were to face GGG and Kovalev in a row and win both.


So, Ward didn't at all accept Loefler's challenge of 50/50 and 164. It's basically more of the same jawing from both sides. No progress has been made at least not publicly.
