Banik Ostrava and Sparta Prague have been fined for crowd trouble during their Czech league match over the weekend.
On Saturday, the clubs' fans clashed violently with police during the 1-1 draw in Ostrava.
Officers arrested 30 fans and the start of the second half between the fierce rivals had to be delayed by 30 minutes.
The Czech football federation's disciplinary committee fined Banik 300,000 koruna ($A16,240) while Sparta has to pay 50,000 koruna.
Banik will also have its stadium closed for two league matches if such an incident happens again this year.
Following Saturday's clash, federation head Miroslav Pelta said he will work with the government to enact tougher rules to tackle football hooliganism.
