Felipe Nasr has admitted that he could lose his Formula One drive.
The Brazilian driver is currently in negotiations to remain at Sauber, although the team are also thought to be talking with Mercedes over the possibility of Pascal Wehrlein driving for the team.
However, should Nasr miss out, and Felipe Massa doesn't come out of retirement to replace Valtteri Bottas who is thought to be on his way to Mercedes, there is a chance that Formula One could be left with no Brazilian drivers on the grid.
"I think it would be bad for the sport," Nasr told Brazil's Globo.
"Brazil has so much history in formula one but I don't think it's going to happen. But there's always the risk.
"I want to be on the grid and I'm working towards this."
"It is very unusual in Formula One to be at this time of year and have so many vacant places. I think it's just a matter of continuing to negotiate and trying to find a place," he added.
