Borussia Dortmund have banned a supporter from their stadium until 2020 for shouting "Sieg Heil" during a minute's silence before Saturday's game at Hamburg SV.
Dortmund said the man was led away by Hamburg stewards after the Nazi salute and given a three-year nationwide ban from football stadiums. Although that is the maximum allowed for a nationwide ban, Dortmund added their own six-year ban on top.
The man, who was not identified, interrupted the silence to honour former Hamburg physiotherapist Hermann Rieger, who died last week, Dortmund said in a statement.
"Borussia Dortmund stands for tolerance and diversity with the utmost conviction and will fight against racism and intolerance with every available means," the club said.
