The Danish fan who attacked a referee during a Euro 2008 qualifier between Denmark and Sweden in June was sentenced to 20 days in jail by an appeals court.

The 29-year-old man, who remained unnamed, was convicted of attempted assault and trespassing by the Eastern Court of Appeals, overturning an earlier suspended sentence of 30 days plus 40-hours' community service.

The man attacked Herbert Fandel when the German referee sent off Denmark's Christian Poulsen and awarded Sweden a penalty in the closing minutes of the match on June 2.

Denmark's Michael Gravgaard managed to keep the drunk man away from Fandel, who opted to abandon the Group F match, with the teams tied at 3-3. Sweden were later awarded a 3-0 victory by UEFA. "The assault was only prevented because Michael Gravgaard physically stepped in and it is apparent from video footage that the defendant was very determined in his actions," the court said in a statement.

Denmark failed to qualify for next year's European championships while Sweden took one of the group's two qualifying spots alongside Spain.

The man has admitted to drunkenness and to entering the field illegally.
