However, racing pundit Richard Bradley believes there is another driver - eight-time race winner Daniel Ricciardo - at risk of being cut by RB ahead of the upcoming Emilia Romagna Grand Prix.
'The writing's on the wall'
The Australian experienced a mixed weekend in Miami, driving exceptionally to grab a fourth-place in the sprint event, before finishing 15th in the main race on Sunday.
It was to be another disappointing result in a campaign littered with below-par performances, and Bradley thinks the 34-year-old may have run out of time to turn his fortunes around, with reserve driver Liam Lawson poised to step in.
When asked on the On Track GP F1 Podcast whether Ricciardo will be in the seat at Imola, Bradley said: “I don’t think so, no.
“If you just look at it, it was one quali and one race he did a very good job in that, but let’s actually look at it in terms of overall at the beginning of this year.
“That’s two good sessions out of how many? I’m sorry but I think the writing’s on the wall. Liam Lawson is proven, he’s right there.”
