Haas Formula 1 driver Kevin Magnussen is set to skip Formula 1's Friday track action at the Brazilian Grand Prix due to being waylaid with what his team has described as an unspecified sickness.

The 32-year-old Dane will be replaced in the Haas VF-24 by Ollie Bearman, who will be a full-time Haas F1 driver next year.

A request for Bearman to stand in for Magnussen "until further notice" has already been granted by the FIA stewards.

It means that he will run in the sole practice session of the Interlagos weekend - which is being held under a sprint format - and then qualify the VF-24 for the sprint race.

Haas says it "wishes Kevin a quick recovery and will provide a further update in due course".

Its announcement suggests there is hope that Magnussen can retake his seat later in the weekend, but if he is definitively ruled out of Saturday action, that would mean by rule he cannot contest the sprint either.

So the only point of the weekend at which Magnussen could return would be in grand prix qualifying on Saturday afternoon.

Bearman had already stood in for Magnussen earlier this season in Baku, when Magnussen was serving a one-race ban.

He'd also raced for Ferrari in Jeddah in relief of an appendicitis-stricken Carlos Sainz.

Ferrari still needs one more rookie FP1 outing to fulfill its quota for the season, and Bearman - who it ran in that role in Mexico - would be ineligible to serve as its rookie driver if he adds an extra grand prix start this weekend, taking his total up to three.

Just a sprint start, however, would not count.
