Two-time world champion Fernando Alonso brought the morning session on the final day of the second pre-season testing in Barcelona to a premature end when he crashed the McLaren-Honda MP4-30.
The Spaniard had managed just 20 laps on another troubled morning for the struggling giants, who lag well behind every other team on the grid in terms of mileage with the start of the season less than a month away.
Alonso received medical attention and was airlifted to hospital after the crash, but circuit officials said he was "OK and conscious."
Jenson Button was already scheduled to take over from Alonso for the afternoon session having been very limited in his running on Thursday and Saturday due to a faulty seal.
It was a much more positive morning for the other Spanish driver on show as rookie Carlos Sainz Junior was fastest in the Toro Rosso in a time of 1min 25.604.
Sebastian Vettel was second quickest for Ferrari, whilst Mercedes continued their mileage marathon in testing as Nico Rosberg logged another 68 laps despite an early spin-off into the gravel.
