The 21-year-old sealed the 9th knockout victory of his career last time out against Razvan Cojanu in two rounds at the Royal Albert Hall in March.
That fight represented another step up in class for the Londoner, with Cojanu challenging for the WBO heavyweight title as recently as May 2017 against Joseph Parker.
Dubois’ previous fight came up against the durable Kevin Johnson, a former opponent of Anthony Joshua and Tyson Fury who held on all 10 rounds before losing on a points decision.
Ghana’s Lartey, whose only defeat came through an injury-enforced retirement, believes Dubois has been spoon-fed poor opposition however.
Believing he himself has been an avoided man in the heavyweight division, he has vowed to deliver a shock in the capital.

Dubois is making rapid progress and is regarded as one of the heavyweight's brightest young talents.
While Lartey may have a point over some of his previous opponents - see Dubois' chilling knockout win over AJ Carter in 2017 - the Johnson and Cojanu fights have represented fair tests he has passed comfortably.
Having rediscovered his destructive touch last time out, knockout no.10 could be on the way this weekend.
- Lerrone Richards vs Tommy Langford
