Dubois, known as 'DDD', has been on a roll. He's beaten three top opponents in a row. Last December, he knocked out Jarrell Miller in the 10th round. Then in the summer, he stopped Fillip Hrgovic due to cuts. In September, he beat Anthony Joshua more decisively than anyone else has before, defending his IBF Heavyweight Title.
Parker has also turned things around after a tough loss to Joe Joyce. He beat Deontay Wilder on points last December. Earlier this year, he won another points decision against Zhilei Zhang, even though Zhang knocked him down twice.
Nick Campbell, a Scottish heavyweight who's trained with both fighters, thinks it's an even match. He's been in Parker's camp for five of his last fights and worked with Dubois before the Hrgovic and Joshua fights.
Campbell said, as he told iFL TV:
"Dubois has been unbelievable in his last three fights with big wins. Parker has beaten Wilder and Zhang, two imposing wins. They're polar opposites in personality and approach. Dubois is an aggressive power puncher. Parker is more adaptable and can change his game plan. He's got more tricks up his sleeve."
Campbell thinks Parker will win. He believes Parker is more adaptable, has a better boxing brain, and hasn't reached his best yet.
The fight will be part of a big event in Saudi Arabia. The main event will be a rematch between Artur Beterbiev and Dmitry Bivol for the undisputed light heavyweight world championship.
