According to the Daily Mail, the footballing federation could clamp down on those clubs who failed to release their players for international duty.
This stems from the fact Zenit decided to recall Brazilian duo Malcom and Claudinho from their national team in order to have them available to face Chelsea on September 14th.
Zenit travel to Stamford Bridge for their first European tie in just under two weeks, eager to field a full-strength squad against the reigning champions.
They feared Malcom and Claudinho would not be eligible to play had they gone away with Brazil, due to quarantine rules about returning from countries on the UK’s red list.
However, they might still miss out thanks to FIFA’s laws about individuals not being allowed to represent their nation, despite being asked to do so.
There is a possible five-day ban for those who were not discharged by their domestic employers for the international interlude.
This could come back to bite Chelsea as well, who denied Silva the opportunity to jet off with Brazil.
Although the 36-year-old is not a regular for Thomas Tuchel, his experience on European nights has proved crucial.
He might also be in contention for a start, as the Blues host Aston Villa just three days before Zenit arrive in South West London.
Brazil may lodge a complaint to FIFA, with the aim of lowering the five-day ban to a maximum of two days.
