Joshua is just shy of three months older than Prenga, but their careers have followed very different paths.
After winning gold at the 2012 Olympics, Joshua turned professional the following year and went on to become a two-time heavyweight world champion.
Joshua won each of his first 16 fights inside the distance in a run that culminated in him beating Charles Martin to claim the IBF title.
His crowning moment came in 2017 when he stopped Wladimir Klitschko in the 11th round at Wembley to unify titles – adding the WBA belt to his collection.
In 2018, Joshua outpointed Joseph Parker – winning by unanimous decision – to claim the WBO title.
Joshua tasted defeat for the first time against American Andy Ruiz Jr in 2019 but earned revenge to reclaim the titles in a rematch.
He was beaten in successive fights by Oleksandr Usyk in 2021 and 2022, before embarking on a four-fight winning streak to earn the chance to become a three-time world champion.
However, fellow Briton Daniel Dubois, who held the IBF belt, put in a career-best performance to beat Joshua by sixth-round knockout in September 2024 at Wembley Stadium.
Joshua returned to the ring in December 2025 and stopped YouTuber-turned-boxer Paul to take his overall record to 29 wins and four defeats, with 26 of his victories coming by knockout.
Prenga made his professional debut three years after Joshua and won his first four fights by knockout.
The Albanian fell to his first and only loss in his fifth bout and steps into the ring on Saturday on a 16-fight winning streak, although he does not have any recognisable names on his record.
Prenga does carry a knockout threat after picking up all 20 of his victories in that fashion.
