Lance Stroll's first day of Formula One testing came to a premature conclusion on Tuesday, with Williams forced to halt their participation due to damage sustained when the Canadian newcomer spun out.
The 18-year-old, handed a senior seat alongisde the returning Felipe Massa, managed 12 laps at Circuit de Barcelona-Catalunya.
But a spin encountered at turn nine saw his FW40 enter a gravel trap, leaving the front wing requiring repairs that could not be completed before Wednesday.
"It is still early days and I have only done a handful of laps," Stroll said.

"I am just getting to grips with the FW40, and there is still a lot of time ahead of us. It was good to finally get behind the wheel to just get a feel for it.
"Like I said, it is still early days, so I need to do a lot more running before I know exactly where I am and where the car is at.
"I will have a much better picture once we have more laps under our belts, but it was good to break the ice and I am looking forward to some more running."
Williams' Rob Smedley added: "Even though the accident was entirely innocuous we've unfortunately had quite a bit of accident damage, which we're now in the process of repairing.
"We're having to send some composite parts back to the factory, which will be back with us at some point tomorrow.
"We're doing the utmost we can now to get back out on track at the earliest opportunity tomorrow. We will be able to recover the programme in the coming days."
There was a familiar face atop the time charts after the morning session on Tuesday, with Mercedes' Lewis Hamilton, heavy title favourite in the absence of retired champion Nico Rosberg, two seconds clear of Ferrari's Kimi Raikkonen.
