Anthony Joshua did not watch heavyweight rival Tyson Fury's latest bout as he is fully focused for the "biggest pressure fight" of his career against Alexander Povetkin, according to his promoter Eddie Hearn.
Unbeaten Briton Joshua will put his WBA, IBF, IBO and WBO titles on the line against Russia's Povetkin at Wembley on September 22.
Joshua had hoped for a lucrative unification bout with WBC champion Deontay Wilder, but negotiations between the camps broke down.
Wilder is instead expected to seal a bout against Fury, with the American in attendance for the former unified heavyweight king's points win over Francesco Pianeta earlier this month.
Joshua himself could find himself on a collision course with Fury should he defeat Wilder, but Hearn says all future plans are being put on the shelf as the 28-year-old is refusing to look beyond his showdown with Povetkin.
Speaking to Sky Sports, Hearn explained: "I said to him [Joshua], 'Did you watch that?' and he said 'What?'
"It was later that night and I said 'The Fury fight?' He said 'No, what happened?'
"He's so focused on this camp, because he knows about Povetkin. People in boxing know about Povetkin. Anyone you ask in boxing goes: 'It's a tough fight'.
"I don't think he's in the mood to be thinking about other stuff, talking about other stuff, outside of Povetkin.
"I don't think he's taking a lot of interest in the outside world around this fight, because he knows what's at stake.
"Obviously people have told him he might be fighting [the winner of] Fury-Wilder, but he's just going to concentrate on what we're doing.
"I think he thinks this is the toughest fight of his career because of what's around, what people are talking about beyond this. I think this is the biggest pressure fight of his career so far."
