British heavyweight boxer Anthony Joshua has been injured in a car crash in Nigeria, which killed two members of his team. The former world champion was a passenger in a vehicle that collided with a stationary truck on a major expressway in Ogun State, near Lagos. The two men who died were Joshua's close friends and team members Sina Ghami and Latif 'Latz' Ayodele, the boxer's promoter Matchroom Boxing said in a statement. It added that Joshua was in a stable condition in hospital, where he was taken for 'checks and treatment' and will remain for observation. 'Our deepest condolences and prayers are with the families and friends of all those affected - and we ask that their privacy is respected at this incredibly difficult time,' the Matchroom statement said. The group's chair, boxing promoter Eddie Hearn, paid tribute to the 'two great men' who were killed in the crash. 'Rest in eternal peace Sina and Latz. My thoughts and deepest prayers are with everyone,' he said. Boxing expert Steve Bunce described Mr. Ghami and Mr. Ayodele as 'two of Joshua's closest friends' and as 'massive parts of the Anthony Joshua machine'. Hours before the crash, Joshua posted a video to Instagram of himself and Mr. Ayodele playing table tennis. The crash took place on the busy Lagos-Ibadan expressway at around 12:00 local time (11:00 GMT). The incident involved two vehicles: a black Lexus and a stationary red commercial truck. Nigeria's Federal Road Safety Corps (FRSC) said the Lexus was 'suspected to be travelling beyond the legally prescribed speed limit', based on preliminary findings. Local officials said Joshua and another man - the vehicle's driver - were rescued by the boxer's security team. The Lagos-Ibadan expressway is known as one of Nigeria's deadliest roads, with particularly heavy traffic at this time of year as many Nigerians living abroad visit for the festive period. Joshua, who was born in Watford, has family roots in Sagamu - a town in Ogun State, near the crash site. The boxer's family is well known in the town and traces its ancestry there across several generations.
