OLEKSANDR USYK was left grimacing after watching back Anthony Joshua's brutal knockout of Francis Ngannou.
Joshua floored Ngannou three times in two rounds with the final ruthless right hand finishing the job.
But Usyk might not have even seen the final blow having refused to watch on after AJ's second knockdown.
DAZN played back the fight to the Ukrainian and his reaction to Ngannou, 37, hitting the deck for the second time was that of shock.
And he closed the laptop down to watch on no more, missing the moment the MMA star got to his feet only to be KO'd with the very next punch.
Anthony Joshua advised to "play the game" by heavyweight boxing legend
Usyk, 36, returns on May 18 in the heavyweight division's first four-belt unification bout against Fury, 35.
The pair are contracted to rematch right after but Joshua, 34, will hope to muscle his way into a title shot.
And AJ - who has twice lost to Usyk - insisted he is just a phone call away if either want to get a deal done.
He told Sky Sports: "For my career, I feel like wins are just left in the past, you can't dwell on them too long because there's always another challenge coming up.
"I feel like a win just moves me onto not dwelling in my sorrows to much because a loss isn't nice for anyone.

"And then in terms of Usyk and Fury, it's really up to them. I'm only a phonecall away, even better, I'm only a tweet away. You can tweet me and we can make the deal, so it will happen."
On the Fury bout, Joshua said: "I'll fight him in his back garden, it doesn't matter to me. I'm a fighting man, you know what I'm saying?
"Wherever, whenever, however - it doesn't matter. As long as we deliver for the fans, that's the main thing."
