Anthony Joshua has dropped down the Ring Magazine's heavyweight rankings following his defeat by Oleksandr Usyk.
The Briton was defeated on points by Usyk on Saturday night with the Ukrainian snatching Joshua's unified world titles in London.
The 31-year-old was unsettled by the technique and footwork of his opponent, dominating large parts of the contest.
And Joshua has now fallen one spot from No.1 contender to No.2 in the respected rankings.
His opponent Usyk has risen above him, with American heavyweight Deontay Wilder behind him in third position.
Joshua's domestic rival Tyson Fury currently holds the belt, with Wilder set to challenge him in a trilogy bout next month.
The former two-time champion now faces a long path of redemption to secure a shot at Fury, with a rematch with Usyk planned next.
And he has uncovered what went wrong during his defeat on a huge night for British boxing against Usyk.
“I’m not a sulker,” he said bullishly after the fight. “This is a blessed opportunity to be able to fight for the heavyweight championship of the world.
“I’m not going to go home tonight and be crying about it because this is war. It’s a long process. This isn’t just one fight and I’m done. I can’t go back and sulk, that’s a waste of time.
“I’m going back to look at ways I can improve, straight away. I’ve already looked at the fight. When I walked back through the tunnel, I said to myself, ‘I’m ready to get back into the gym’.
“It was a great experience and we’ve progressed once again, you’ve got to trust the process, good or bad. I can’t look at it and have any regrets. I believe I will get a good win in the next fight because of what I did in this fight. It was a great lesson. I’m a quick learner and I’ll bounce back.”

Joshua's team appeared to be in denial over the situation that emerged during the fight, where he was tactically outclassed by his opponent.
But he has since hinted that his gameplan to outbox the technical Ukrainian, was the wrong approach to a cat-and-mouse contest.
"I let a few people down, obviously people that support me. There's other people that probably thought I should have gone in with a different gameplan," he told iFL TV.
"But at the end of the day he won and I lost. All I want to do is get back to the drawing board, hustle and put in the work. Over the period of time I'm boxing, just change the script, get another W and fight for the belts again.
"There's certain things I know I can improve on for sure and there's certain things that he can probably improve on, that's why I feel like the next fight will be phenomenal."
"I've got a great opportunity of becoming three-time heavyweight champion of the world, so I'm going to take it with both hands and put the work in."
