Jenson Button will not take part in qualifying for the Canadian Grand Prix as his MP4-30 suffered an ERS failure in FP3.
Button brought out the red flags late in Saturday's final practice at the Circuit Gilles Villeneuve when his car lost power, grinding to a halt at Turn 7.
The MP4-30 reportedly suffered an ERS-related failure and as such needs an engine change with McLaren confirming Button will have to sit out qualifying.
The team tweeted: "JB's car suffered ERS-related failure towards the end of FP3.
"Our engineers are looking at data, but sadly his car won't be ready for quali."
