British heavyweight boxer Anthony Joshua has been discharged from hospital in Nigeria days after a fatal car accident that killed two of his close friends.

The former world champion was deemed fit to recuperate at home, the Ogun and Lagos states said in a joint statement, describing him as 'heavy hearted' over the loss of his friends.

The 36-year-old was a passenger in a Lexus SUV that collided with a stationary truck on a major expressway in Ogun State, near Lagos, on Monday.

The two men who died were Joshua's close friends and team members Sina Ghami and Latif 'Latz' Ayodele.

After leaving the hospital on Wednesday, the Briton visited the funeral home where the bodies of his friends were 'being prepared for repatriation', the joint statement added.

Earlier, Eddie Hearn, who has promoted Joshua since he turned professional after winning gold at the 2012 Olympics, paid tribute to Joshua's close friends and 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.'

Ghami was Joshua's full-time sport and exercise rehabilitation coach and worked with him for more than 10 years.

Speaking to the BBC, Ogun State police spokesperson Oluseyi Babaseyi mentioned that 'investigations are still ongoing' regarding the incident. Preliminary investigations indicated that the vehicle had burst a tyre before crashing into the truck.

Joshua, who was born in Watford to Nigerian parents, was on holiday in Nigeria after winning a recent bout against Jake Paul in Miami.

Condolences from boxing figures and fans continue to pour in as the boxing world mourns the loss of the two men.
