Joshua, 36, was a passenger in a Lexus SUV that collided with a parked truck on the busy Lagos-Ibadan expressway, in south-west Nigeria, on Monday.
Mr Ghami and Mr Ayodele were both pronounced dead at the scene, while Joshua was pictured being helped from the wreckage.
Ogun and Lagos state officials said in a statement that the British boxer was “heavy hearted” over the deaths of the two men, who were both his close friends.
After being discharged from hospital, Joshua visited the funeral home where their bodies were “being prepared for repatriation”, the statement added.
Just hours before the crash, Joshua posted a video to Instagram of him playing table tennis with Mr Ayodele.
On Monday, Eddie Hearn, who has been Joshua’s promoter for more than a decade, paid tribute to the team members.
“Rest in peace Latz and Sina,” Hearn posted on Instagram.
“Your energy and loyalty among so many other great qualities will be deeply missed. Praying for strength and guidance for all their family, friends and of course AJ during this very difficult time.”
