Sebastien Loeb is under investigation for his rapid tyre change during SS11 of Rally Sardinia.
FIA stewards are investigating whether or not Loeb and co-driver Daniel Elena acted according to the WRC rule book during the incident, which occurred while Loeb was battling Mikko Hirvonen for second place.
Loeb and Elena managed to replace a puncture in little more than a minute during the stage but the FIA has now launched an investigation which is believed to be linked to seat-belt regulations – which should be worn at all times while the car is moving.
In-car video footage is believed to show that one of the pair had removed their seat-belts before the car came to a halt.
Stewards are expected to announce their findings later today, but Loeb could possibly face exclusion from the event if it is deemed that regulations were broken in the incident. Should Loeb be excluded, it could breathe new life into the championship races, with Mikko Hirvonen currently second and Ford holding a 1-2 at the head of the field.
