Celtic have been fined nearly £9,500 over two charges of misconduct during last month's Europa League second-leg meeting with Inter Milan.
A penalty of £5,860 was imposed for "improper conduct" on the field as well as a £3,600 punishment for flares set off by fans at the San Siro.
Virgil van Dijk was sent off for two bookable offences, while five other players were booked in the 1-0 loss.
Uefa fined Celtic earlier this year for supporter behaviour at Dinamo Zagreb.
And this is the seventh time the Glasgow club have been penalised for the actions of fans since December 2011.
Inter, who proceeded to last 16 of Europa League with a 4-3 aggregate victory - only to lose out to Wolfsburg, were also fined £3600 for their supporters letting off fireworks.

In a statement, Celtic said: "Clearly Celtic Football Club is disappointed by today's decisions.
"It should be noted that Celtic players have an excellent disciplinary record in European football over many years and in Scotland, Celtic has been top of the league's disciplinary table for the last three years, something which we are rightly proud of.
"Again, it is disappointing that the actions of one or two individuals within a support of well over 3,000, have let the club down by using flares at this match."
