John McGuinness has suffered a suspected broken leg while in action at the North West 200 in Northern Ireland.
The Morecambe Missile came off during Superbike qualifying at an event which is major part of the 45-year-old’s road racing season.
Any injury will likely put his participation in this year’s Isle of Man TT in jeopardy, the first practice session getting underway in just 16 days on Saturday May 27.
McGuinness is a 23-time winner at the iconic festival of racing, second on the all-time list.
He also has six North West 200 victories to his name.
Honda Racing said in a statement: “During Superbike qualifying at the North West 200 today, Honda Racing’s John McGuinness was involved in an incident at Primrose Hill.
“Within a short time of the incident John was transported by ambulance to Royal Victoria Hospital in Belfast where he is currently undergoing treatment for a suspected broken right leg.
“The Honda Racing team and John would like to thank the prompt action of the marshals, circuit staff and emergency services.”
