Boxing superstar Anthony Joshua has been released from a Nigerian hospital after being involved in a car wreck that killed two of his trainers.

Anthony, a former heavyweight champion and Olympic gold medalist, was discharged late Wednesday afternoon and will continue his recovery from home … according to authorities in Nigeria.

As we reported … Anthony was under observation at a hospital in Lago after Monday’s fatal car crash.

The boxer’s strength and conditioning coach, Sina Ghami, and his trainer, Latif Ayodele, died in the crash. The three were all close friends.

Joshua was sitting in the backseat when the car he was riding in crashed into a stationary truck on a crowded expressway in Nigeria.

The crash came a little over a week after Joshua won a boxing match with Jake Paul.
