Sebastian Vettel believes a bump in the road could have been the culprit that led to him taking part in qualifying on Saturday with a very sore neck.
Although he finished hot on the heels of poleman Lewis Hamilton, Vettel struggled during the all-important 60-minute session, with bandaging added to support his neck.
"It wasn't the most enjoyable session," admitted the Ferrari driver who will line up alongside Hamilton on the British Grand Prix grid.
"We've loosened it up and I think the night will help for the race. I'm not worried," he said yesterday.
"The speed is less than in quali because you have more fuel and we're a bit slower so it's going to be ok."
Asked what caused the neck problem, Vettel joked: "Maybe it's the stewards' fault from last week. I was looking in the mirrors too intensely!
"I don't know. Maybe I hit a bump."
Drivers have taken aim at Silverstone's bumpy surface and a new tarmac applied back in February apparently hasn't made it any smoother.
"The big bumps are gone but there's a lot of new ones now," said Mercedes' Valtteri Bottas.
"There is no bumpier track on the calendar than Silverstone."
Hamilton echoed his team mate's view, claiming the resurfacing work at Silverstone since last year's British Grand Prix was the "worst" he has ever encountered.
