Lance Stroll sent a concerning message to his Aston Martin team during practice on Friday which raised questions over his fitness ahead of the Bahrain Grand Prix.
The Canadian is attempting to complete the race weekend despite suffering an injury during pre-season training. He missed testing after crashing while riding a bicycle in Spain – an injury which required surgery to fix.
Reserve driver Felipe Drugovich filled in for Stroll during testing and is on standby in Bahrain this weekend in case he is needed. Stroll intends to race, but a worrying message sent during the second practice session of Friday indicated that he could struggle to do so.
