Russia internationals Kokorin and Mamaev sentenced to a year and a half in prison
The Russian internationals, who both featured at Euro 2016, were found guilty in Moscow after spending the last 7 months in custody.
Kokorin and Mamev attacked two cafe workers and beat up a driver in the Russian capital, before attacking a trade ministry official with a chair after he challenged their behaviour in October of 2018.
The defence's claim that their clients were reacting to provocation and insults from those in the cafe were waved away, and the verdict was met with tears and disbelief from the players' families, who insisted that the footballers had learnt their lesson.
In addition, Kokorin's younger brother Kirill and their friend Alexander Protosavitsky have been found guilty.
The punishment for hooliganism in Russia is a maximum penalty of seven years in jail.
Kokorin, 27, has 48 caps for Russia, but missed last year's home World Cup through injury, while 30-year-old Mamaev has 15 caps.
