Two Russians were convicted of permanently disabling a British football supporter in southern France during the Uefa Euro 2016 tournament.
Spartak Moscow fan Pavel Kosov was sentenced to 10 years in prison, while Mikhail Ivkin was given a three-year sentence.
They had been on trial in the southern French port city of Marseille accused of “gang violence with weapons, leading to permanent infirmity”.
They had been held in prison in France since March 2018.
The pair attacked Andrew Bache, 55 and from Portsmouth, during the European football championships in June 2016.
His son Harry represented him in court and faced his father’s alleged assailants.
Mr Bache’s lawyer, Olivier Rosato, said that the attack left his client severely disabled and he can no longer bear to return to Marseille.
“It’s a decision that satisfies the family.
“They wanted Kosov’s sentence to be severe because he was the first to punch Andrew, and from behind, causing him to smash his head on the ground, which was granite,” Mr Rosato said.
Mr Rosato said that the two have also been banned from returning to France after they have served their sentences.
Witnesses to the incident say they saw Mr Bache being caught by hooligans, and receiving three or four violent blows to the head, including while he was floored.
The riots in Marseille’s Old Port district lasted for several days, both before and after a match between England and Russia.
Police fired tear gas and water cannons at rival fans who were rioting around the city, a largely unsuccessful attempt to rein in violence that authorities said left several people injured.
Some fans walked through the city bare-chested and with blood dripping from head wounds.
French interior minister Bernard Cazeneuve said at the time that “once again, as over the last 30 years, an international football competition has been the scene of clashes between violent people claiming to be supporters of their national team”.
