Joshua's personal trainer, Latif Ayodele, and strength coach, Sina Ghami, died on 29 December after their vehicle collided with a stationary lorry near Lagos, Nigeria.

The former world heavyweight champion, 36, was treated in hospital for his injuries.

Adeniyi Mobolaji Kayode, who was driving Joshua when their car crashed, has been charged with causing death by dangerous driving, reckless and negligent driving, driving without due care, and driving without a valid driver's licence.

The 46-year-old appeared at Sagamu Magistrates Court in Ogun state near Lagos on Wednesday, when the case was adjourned until 13 March.

Prosecutors told the court they needed further time to prepare evidence.

Joshua was discharged from hospital two days after the Lexus SUV crashed on the busy Lagos-Ibadan expressway, in south-west Nigeria. Ghami and Ayodele were both pronounced dead at the scene.

Kayode, who was making his second appearance at court, is yet to enter a plea.
