Pirelli and Renault are continuing analysis on the cause of Jolyon Palmer's tyre failure during practice for the Spanish Grand Prix.
Palmer suffered a high speed failure along the pit straight though was able to come to a safe halt in the run-off at Turn 2.
It was the second failure in as many sessions for Renault, after test and reserve driver Esteban Ocon was affected by a puncture in the opening encounter.
"Esteban did a good job for his brief time in the car and we’re looking forward to him getting a proper crack at the whip in next week’s test," said Technical Director Nick Chester.
"His puncture looked to be a clear cut case of a small piece of debris piercing the tread and we have no ongoing concerns about the battery issue which subsequently stopped him running.
"Jolyon was also unfortunate with a puncture and we are working with Pirelli to understand the cause."
