An elderly cyclist found at the side of a rural Co Londonderry road is thought to have been struck by a passing vehicle.
Motorists spotted the 73-year-old lying injured on Shore Road in Ballyronan, Magherafelt, on Saturday morning.
He is thought to have been knocked off his bike on the country road earlier the same day.
Ambulance crews took the man to Antrim Hospital where he is now in a stable condition.
Police in Magherafelt are appealing for anyone who saw the man to get in touch.
Constable Kernohan said: "Motorists discovered a 73-year-old male lying on the Shore Road close to the junction of the Oakleigh Road, Ballyronan at approximately 10.30am on Saturday. They called an ambulance and he was taken to hospital.
"Later that afternoon police were contacted after medical staff expressed concern that the cyclist's injuries may suggest he had been struck by a vehicle.
"The cyclist was wearing a white and black coloured top and cycling shorts. A gun metal grey helmet, black and lime green gloves, silver rimmed glasses and white cycle shoes. If you believe you saw this male or have any information that can help us, please call police in Magherafelt on 101 quoting reference 793 of 06/08/16."
Keen cyclist and Sinn Fein councillor Gavin Bell said he frequently rode in the area. He said: "Cyclists are taking their life in their hands when they head out. There's not a day when I'm out where motorists aren't cutting me off or passing when there's on coming traffic - people seem to have less and less patience.
"Motorists aren't treating cyclists with the same respect they have for other road users. They are putting the cyclists' lives, their own lives and that of other road users at risk overtaking at dangerous times and I would call on the local authorities to do more to highlight the issue."
