“I think AJ, as we have seen in the past on boxing-related stuff, is always a brave-face guy, a very positive guy,” Hearn told Sky Sports.
“This is very different to that and I know he will take his time.
“He will need his time physically, mentally, emotionally, spiritually before he makes a decision on his future. I do think he will want to return to boxing, but that will be his decision when the time is right.”
The crash happened while Joshua was on holiday in Nigeria following his win against YouTuber-turned-boxer Jake Paul in Miami on December 19.
Both Ayodele, the personal trainer of the former two-time unified heavyweight champion, and Ghami, Joshua’s strength and conditioning coach, died at the scene of the crash.
Before the accident, there was fresh talk of a long-awaited bout between Joshua and Tyson Fury, the former world heavyweight champion who recently came out of retirement.
But Hearn said Wednesday: “That is not a conversation that anyone is comfortable having… When the time is right, I believe he will make his decision and you will hear it from him.”
