The scandal came to an end quickly: a Nottingham Forrest fan was sentenced to prison after a brutal attack on Sheffield’s Billy Sharp after a storm in a duel between the two teams on Tuesday.

Prison sentence: Robert Biggs, the fan who headbutted Sheffield’s captain Billy Sharp in the semi-finals of the English Premier League’s promotion round, was sentenced to five and a half months in prison by a court in Nottingham on Thursday, the Daily Star reports.

Ban for life: Season ticket holder Biggs pleaded guilty, but charges of illegally entering the interior were dropped. Biggs did not appeal the motion to be banned from football stadiums for life. Nottingham play Huddersfield for promotion to the Premier League on Sunday.

Huge damage: Marianne Connally, District Attorney for the East Midlands report, said: “This was an extremely serious and unprovoked attack which resulted in a professional footballer standing on the sidelines needing stitches.” She added: “Biggs gave the club and his Fans spoiled an incredible moment. As a result of his actions, he will not be able to see his club play in the Premier League should Forest win the Championship play-off final.”
