The 72-year-old remains in hospital with serious head injuries after the fight last night outside the North Star pub in Finchley Road, Swiss Cottage.
A second man in his 40s, believed to be the pub landlord, was also taken to hospital for treatment for non-life threatening injuries.
No arrests have been made.
Finchley Road southbound is down to one lane and part of the pavement is closed.
