Twelve men and four teenage boys have appeared in court in connection with clashes before a football match between Bradford City and Sheffield United.
Nine of the men are charged with causing grievous bodily harm to a man in Market Street, Bradford, ahead of a Championship game on 22 October 2016.
Eight of them are also charged with affray at the same location.
Four men and four teenagers are also charged with affray in Manningham Lane on the same day.
All 12 adults, who are from the Bradford area, appeared at Bradford Magistrates' Court.
They were bailed to appear at the city's crown court on 18 April.
Three of the teenagers, two aged 15 and one aged 17, from the Bradford area, are due to stand trail at Bradford Magistrates' Court on 26 April.
A fourth youth, aged 15, from Bradford, was given a football banning order for three years after the charge of affray was withdrawn.
