Anthony Joshua isn't the only sporting AJ! Before he meets Eric Molina, live on Sky Sports Box Office on December 10, we consider the power of those initials...
Andrew Johnston
Golf's fun-loving AJ, affectionately known as 'Beef', has swiftly become a marquee personality on the European Tour. He claimed his first European Tour title at the Spanish Open earlier this year, celebrating accordingly, and his contagious smile is an abiding memory from the 145th Open at Troon.
Alec James Stewart
Okay, so we included his middle name. But Stewart, former captain of the England cricket team, is an OBE so deserves special inclusion.
The batsman-wicketkeeper is second most-capped Test match Englishman (133) and third-most for ODIs (170).
AJ Styles
A late-bloomer in the world of WWE, but this AJ has swiftly ascended to the top of the sport and become a world champion in the same ilk as Joshua.
Andy Johnson
An eight-cap England international footballer, this AJ opted for speed and precision more than the brute strength of Joshua.
Johnson scored 21 Premier League goals for Crystal Palace in a single season 11 years ago, earning England recognition as a result. He later moved on to Everton, Fulham and QPR but now works back at Palace as a club ambassador.
AJ Green
Adriel Jeremiah Green, better known as AJ to Cincinnati Bengals supporters, is one of the NFL's most exciting wide receivers.
He has featured in every Pro Bowl since turning pro five years ago, and the 260 catches he completed in his first three seasons remains an all-time record.
Anthony Johnson
They nickname the UFC's AJ 'Rumble' and he knocks opponents out with a massive right hand. Sound familiar, boxing fans?
Alan Jones
The first driver to win a Formula One world championship for the Williams team, beginning a lineage that includes Nigel Mansell, Alain Prost and Damon Hill.
Adam Jones
Perhaps the only one of our AJs to outweigh Joshua himself. The Harlequins rugby veteran is a thick 19-stone and that's after a post-Christmas shredding season.
The Wales international, approaching his 100th cap, has also represented the British and Irish Lions and has two caps for the Barbarians.
Adam Jones
A Major League Baseball player never afraid to speak his mind about societal issues. The Baltimore Orioles centre fielder is a five-time MLB All-Star, a four-time Gold Glove Award winner, and a Silver Slugger Award winner.
