An investigation has been launched after Spennymoor Town refused to play the second half of Tuesday’s pre-season friendly against Newton Aycliffe.
Aycliffe had led 1-0 at the break but the match was abandoned when the Moors failed to return to the pitch.
Durham FA told BBC Sport that it would be investigating the incident between the two non-league sides.
Northern Football League Division One side Newton Aycliffe are unbeaten in pre-season, having drawn against Maltby Main and beaten Brandon, Darlington Railway Athletic and Northallerton Town prior to playing Spennymoor.
“In over 40 years as a player, manager and chairman I’ve never seen anything like it,” Newtonians chairman Allan Oliver said.
“Neither team’s physio set foot on the pitch and no players left it through injury so I was as gobsmacked as everyone else, including several Spennymoor players, when they chose not to come out for the second half.
“I am disappointed for our supporters who were enjoying watching us lead against a team two divisions higher than us.”
