Felipe Massa has admitted that he will keep a close eye on former Formula 1 driver Robert Kubica's push to return to the category.
Renault have now confirmed rumours that, after giving the Pole a test at Valencia recently, Kubica will get a more comprehensive outing at Paul Ricard in the near future.
"This second test will be to assess his capabilities to return to the highest level of competition," said team boss Cyril Abiteboul.
The news comes amid speculation that Renault might oust struggling team regular Jolyon Palmer, or at least consider Kubica as an option for a full-time seat in 2018.
Kubica, who said last week his comeback chances are as high as 90%, lost his Renault seat six years ago after his now permanently-injured right arm was partially severed in a rally crash.
When asked about the 32-year-old's comeback attempt, former rival Massa said: "It's very difficult to answer because we don't know exactly how he is and how is his arm.
"It would be fantastic for Formula 1 to have him back but I really hope he's really in the position to be back in the right way and strong enough to do the whole season."
The 2017 championship continues this weekend with the Austrian Grand Prix.
