Daniel Ricciardo and Nico Hulkenberg are due to start the Italian Grand Prix from the back of the grid, the FIA has confirmed.
Penalties have been looming for both ever since the previous race weekend in Spa, with Ricciardo confirming after his early exit in Belgium that a grid drop is on the way.
That is because he has had Renault’s Spec-3 engine fitted in Monza, taking him over the season limit before grid penalties are applied.
The Aussie had some initial trouble with the new power unit in Italy as he experienced a loss of power in FP1, but the problem was rectified for an uninterrupted session in FP2.
Hulkenberg, meanwhile, was already facing a 10-place grid drop for causing a huge crash at Spa which sent Fernando Alonso flying over Charles Leclerc.
With that penalty on the horizon, a tactical engine change has also taken place at Renault, rooting Hulkenberg to the back of the the grid.
Max Verstappen has also taken on a new Spec-B Renault engine and a new MGU-H, but he is still within his season limit so no penalties apply this weekend.
