Anthony Joshua has shockingly decided to switch trainers despite winning his last two matches under the instructions of Derrick James.
AJ will have Ben Davison in his corner and Eddie Hearn has confirmed it is to reduce his travelling.
Speaking on Fight Hub TV, Hearn said: "It's more about the location, I mean, six weeks out, very difficult to fly to Texas and then fly across of time zones to the Middle East.
"He's (Joshua) been training with Ben, the last three or four weeks and Derrick James has been aware of that situation.
"It's comfortable to train in the UK for this fight."
Christmas has come early as Anthony Joshua is set to leave it all in the ring once more against Otto Wallin - and the action unfolds TONIGHT!
AJ is starting to find the form which made Britain fall in love with him again after consecutive wins in his last two encounters.
The British mogul secured a unanimous decision victory against Jermaine Franklin near the beginning of the year, before knocking out Finnish fighter Robert Helenius just four months later.
However, Joshua’s ability and determination has been called into question after the world saw him lose twice to Oleksandr Usyk.
And Wallin will be a big test as the Swede once left Tyson Fury covered in blood, needing 47 stitches.
But AJ seems to not be phased by the criticism and once even bellowed ‘F*** them all’ when asked about his doubters.
One great thing about tonight is that Joshua-Wallin isn’t the only big fight fans are looking forward to as American heavy-hitter Deontay Wilder is on the Day of Reckoning card too.
