Ampthill’s game against Hartpury in rugby union’s Championship had to be abandoned after referee Alex Thomas was hit by a clearing kick during the first half.
He appeared to be knocked out when he was struck by the clearance from Hartpury fly-half Harry Bazalgette, with the visitors leading 14-0 at the time.
Thomas was treated on the field before being taken off on a stretcher.
The game, in the second tier of English rugby union, was called off a few minutes later.
“We appreciate that the decision is disappointing for supporters who have travelled to the game but our priority is for health of the players and match officials,” Bedfordshire side Ampthill said in a statement.
“Our thoughts are with Alex for a swift recovery.”
Hartpury, who began the match fifth in the table and two places above Ampthill, had taken the lead with an Ethan Hunt try.
Aristot Benz-Salomon added a second shortly before the incident which ended the game after 28 minutes.
