Spanish side Granada have said that Sunday's La Liga game against Real Mallorca was abandoned because a linesman was "accidentally" hit by a young fan's flying umbrella.
With half an hour remaining, the home side had just taken a 2-1 lead when the official was struck by an object which appeared to come from the crowd.
"It was really an act of bad luck," said Granada coach Fabri Gonzalez.
"The poor lad still had the handle in his hand and it seems he lost control."
The linesman at the Los Carmenes stadium suffered a deep cut to his cheek, causing the referee to immediately lead his assistants down the tunnel.
It was announced 20 minutes later that the match had been called off and it is unclear when the rest of the game will be played.
"I don't know what decisions will be taken because I haven't had time to think about it yet," said Gonzalez.
"I know that we have, in a very short time, a lot of games between now and Christmas, including the two-legged Copa Del Rey tie against Real Sociedad, and I don't know if there is any week when we could play those minutes."
Mallorca had taken the lead through Victor Casadesus but Granada, who started the game second from bottom, got back into it with goals from Guilherme Siqueira and Carlos Martins.
