FIFA fines Croatia for ambush marketing

FIFA has fined Croatia's soccer federation 70,000 Swiss francs ($A95,500) for an ambush marketing incident by players during a World Cup game.

The sum is a seven-fold increase on the fine FIFA imposed on Russia's soccer body for a fan's neo-Nazi banner at a game.

FIFA says its disciplinary panel fined Croatia for "the display of non-authorised beverage products" by players during their round of 16 win against Denmark on Sunday.

Croatia advanced after a penalty shootout in Nizhny Novgorod.

Long-time FIFA partner Coca-Cola has exclusive rights to supply its brands at World Cup stadiums and sites.

FIFA says it also warned Croatia's federation and goalkeeper Danijel Subasic, who saved three penalties in the shootout.

He then revealed a T-shirt honouring a former teammate who died in 2008 from injuries sustained in a game.

FIFA says Subasic violated equipment rules "due to the display of a personal message."
