I'd imagine that Rupert and his sons are much happier about getting out of the assets after hearing this news.
But this does bring some concern to the overall price that Disney is paying for these assets. The sports assets in the US, Mexico, and Brazil are probably worth around $30-35 billion out of that $71 billion price that Disney is paying for the overall assets. The concern there is that it's highly unlikely that Disney will be able to offload those assets for anywhere near $30-35 billion. At most, those assets seem likely to sell or be offloaded for $20 billion or so.
If there's also issues with the TV assets and Hulu in terms of these payment agreements that Fox had for its shows, that's another negative aspect if it results in substantial payouts to talent/producers/etc.
Regardless, we already knew that Disney+/ESPN+/Hulu are the future of Disney, but they need those bets to go really big now to justify paying what could end up being $40 billion (with $14 billion in additional assumed debt) for 30% of Hulu, Star India, the TV/Movie studio, some international channels, and National Geographic/FX. The price paid just looks very expensive if all the sports assets are removed at a discounted value.
