David Price
On December 10th. Just announced by Eddie Hearns.
Reading his other tweets, it sounds like it's still WBA pendingSource? I'm reading that Price has been installed as the planned opponent IF Wlad turns down the fight. Apparently the balls still in Klitschko court and the Klits-Joshua fight can still be made if he goes for it.
As others have said, that's not Eddie Hearns' Twitter.
If it was anyone else other than the OP, I'd say it's an honest mistake. But seeing who it is... Obvious troll is obvious, maybe?
