Dnipro Dnipropetrovsk have been ordered to play their next home match in European competition behind closed doors as punishment for their fans' behaviour in a Europa League tie.
Uefa has taken the action after fans of the Ukrainian club invaded the pitch, let off fireworks and unfurled a racist banner in Napoli.
European football's governing body also fined Dnipro 70,000 euros (£50,000).
Dnipro won the semi-final second leg at San Paulo stadium 1-0 in May.
That victory saw them progress to the final as 2-1 winners on aggregate, but they were then beaten 3-2 by Sevilla of Spain, who became the first club to win the tournament four times.
Uefa have also punished Dnipro with an "additional match behind closed doors sanction", which will be "deferred for a probationary period of two years".
The eastern Ukraine club, who have been playing home matches 240 miles away in Kiev's Olympic Stadium because of the political situation in the region, qualified for next year's Europa League after finishing third in the Ukrainian league, won by Dynamo Kiev.
