He was found with serious injuries close to the pub off York Road on Wednesday afternoon, police said today.
A West Yorkshire Police spokesman said officers had been called by the ambulance service at about 1.40pm after a man was found with serious injuries.
"The man was taken to hospital and is in a critical condition," he said.
"Enquiries are ongoing but it is not believed there is any third party involvement in the incident."
A previous version of this story said that the man was found seriously injured in an incident at the Old Red Lion pub, York Road, Leeds.
The YEP would like to make it clear that the injured man was in fact found in woodland near the pub, and not at the pub. The original story was based on information given by the police at the time, and the story altered as soon as the further information came to our attention.
