There was actually a journalist, who one would expect to be well informed, who wrote that there was a deal made for Kessler to fight the AA-Stieglitz winner.
I don't think It'll happen since the winner turned out to be Abraham. Abraham is far and away the biggest Star in Germany South of the HW division, and it wouldn't make any Financial sense to risk his career in a fight with Kessler. Had it been stieglitz it would have been different.
Another thing is timing. Kessler is due to fight in October (I think) and AA wont be ready by then.
I think he will fight Magee TBH but we will probably know next week.
