The heavyweight prospect suffered a devastating loss to Joe Joyce in November but has vowed to bounce back after tasting defeat for the first time in his career,
He said of the loss: "It was a devastating setback for me. It was a tough year for everyone with the spread of COVID-19 but I refuse to let this set me back. I will come back and get back to my boxing."
Dubois has now vowed to "iron out" his weaknesses and return to prominence in the heavyweight division.
In a self-recorded video, he said: "I will iron out all of my imperfections and trust me, I will be back with a vengeance."
Dubois suffered a fractured eye socket in the loss to Joyce and his promoter Frank Warren is hoping that he can return to the ring in the coming months.
He said: "The doctor is happy with the way the fractures have healed.
"He has to go back to get his retina looked at again, but hopefully he will then be OK to go again then and get back into full training.
"We want to get him back out in late April or maybe May. All of us are very disappointed with what happened, but he is young and we are not going to rush him into anything."
Dubois faced a social media storm when he was accused of quitting against Joyce but Warren says that his fighter is not interested in keyboard critics.
The promoter explained: "He is not interested in social media, which is very good. He just wants to get on and fight."
