White revealed to ESPN that the 43-year-old Hughes was helping a friend out, when the auto he was riding in collided with a moving train.
UFC Hall-of-Famer Matt Hughes was airlifted to a hospital after his truck collided with a moving train.
Hughes was seriously injured and airlifted to HSHS St. John's Hospital. His condition was not immediately available, but Illinois State Police described his injuries as serious.
It is unknown at this time about how the accident happened and if Hughes was driving the truck, or was a passenger in the vehicle.
Hughes was traveling eastbound on the trail when he approached a rail crossing marked with crossbucks. According to SJ-R.com, the state police are investigating the crash.
The Illinois native retired from mixed martial arts in 2013, a year-and-a-half after suffering a KO loss to Josh Koscheck at UFC 135.
Hughes (45-9) held the UFC's welterweight championship at various points between 2001 and 2006. During a decorated career that saw him emerge as one of MMA's biggest stars - during the sport's biggest growth period - he defeated the likes of St-Pierre, Sean Sherk, Penn, Royce Gracie, Frank Trigg and Matt Serra, among others.
