Joshua fell short for a second time when he faced Usyk in their eagerly anticipated rematch in Jeddah, Saudi Arabia earlier this month.
Admittedly, AJ fared much better in the rematch than the first fight. He even had Usyk on the ropes in the ninth round before the champion came on strong in the latter rounds.
Usyk was announced as the winner via split decision after the final bell and he now looks likely to face Tyson Fury in a massive undisputed fight.
There are still plenty of opponents out there for Joshua, though. Matchroom supremo Hearn thinks bouts against Whyte and Wilder need to happen:
AJ and Whyte have already fought once before, with their all-British clash in 2015 still being one of the best of their respective careers.
With Whyte's last outing being a defeat to Fury, both he and Joshua are at a crossroads with them looking to bounce back from damaging losses.
Joshua and Whyte have improved significantly since their first meeting and they still do not see eye to eye.
It would be a huge stadium-filling fight and so would a clash against Wilder.
The American looked likely to call time on his career after his second defeat to Fury in October 2021.
However, the former world champion is not stopping anytime soon and will face Robert Helenius in his comeback fight at the Barclays Center on October 15.
Wilder's return is great for the division, and on his day, he is still one of the best heavyweights in the world.
His punch power makes him a threat to anyone and the Joshua fight has been clamoured for by fans for years.
It is still one of the best fights to make in the division and like the Whyte rematch, titles do not even need to be on the line to make it a must-watch fight.
