Romain Grosjean could lose his third place on the grid after his Lotus failed a post-qualifying inspection.
The floor of the E21 was found to move too much under when a load was applied to it.
FIA technical delegate Jo Bauer said in a statement: “After the qualifying practice session an asymmetric [right-hand side] front floor deflection test was carried on car numbers one, eight and ten according to Article 3.17.5.”
“Car numbers one and ten were found in conformity with Article 3.17.5 of the 2013 FIA Formula One Technical Regulations.
“However car number eight did not comply with Article 3.17.5 of the 2013 FIA Formula One Technical Regulations as the front floor deflected more than 5mm vertically when the load was applied vertically to it at the point which lies 100mm of car centre line on the [right-hand side].
“I am referring this matter to the stewards for their consideration.”
Failing a technical inspection after qualifying normally leads to the driver in question being excluding from the results and having to start the race from the back of the grid.
