Oliver Bearman will substitute Kevin Magnussen for the complete Sao Paulo Grand Prix weekend after the Dane needed to pull out by means of sickness.
The 19-year-old was initially drafted in just for Friday’s working and the dash race early on Saturday.
However on Friday night the group mentioned Bearman would proceed in Magnussen’s automotive for the rest of the weekend.
Bearman certified tenth for the dash, which is at 14:00 UK time on Saturday, two locations forward of normal driver Nico Hulkenberg.
The Briton will probably be full-time for Haas subsequent season, when Frenchman Esteban Ocon joins the group from Alpine.
Brazil is Bearman’s second aggressive look for Haas in 5 grands prix – he changed Magnussen on the Azerbaijan Grand Prix after he was banned for accruing too many penalty factors on his licence.
