The FIA could yet play a role in the fierce championship battle between Lando Norris and Max Verstappen.
There is a real fight for the Formula 1 drivers' championship this year, with Red Bull star Verstappen top of the standings ahead of McLaren ace Norris at present.
Verstappen opted to take a 10-place grid penalty in Spa before the summer break as a result of changing his engine, effectively ruling out any chance of securing a victory.
Now, there is the possibility of another punishment over the final months of the year, which could land a further blow to his championship bid and thus a boost to Norris'.
According to BBC F1 reporter Andrew Benson, there is talk that the three-time world champion could be forced to take another engine penalty before the season is out, with no talk yet of Norris having to do the same.
Responding to a fan question asking whether this was a possibility for either of the top two drivers, Benson said: "There is no confirmation on either side yet - teams keep these sorts of things to themselves until the last possible moment.
"There is said to be a possibility Verstappen will have take another engine before the end of the season - and therefore get a five-place grid penalty - but that is not confirmed.
"With Norris there has been no suggestion of it, he has not had a penalty yet.
"He has used all his permitted four engines already - but the same is true of every driver."
