Haas will give Antonio Giovinazzi a free practice outing at the upcoming Singapore Grand Prix.
23-years old driver was initially confirmed for practice appearances in Britain, Hungary, Italy, Malaysia, Mexico, Brazil and Abu Dhabi.
However, at Monza, amid the threat of rain, Haas opted to prioritise full-time driver Kevin Magnussen.
In order to make up for the lost running, Haas will field Giovinazzi during FP1 at the Marina Bay Street Circuit.
Antonio, runner-up in GP2 in 2016, contested the first two rounds of the season with Sauber. He replaced of the injured Pascal Wehrlein.
Wehrlein returned for the following grands prix. But Ferrari agreed a deal with its engine customer Haas to field Giovinazzi in seven FP1 sessions over the remainder of 2017.
Giovinazzi was 0.4s slower than Grosjean and 16th in the first of those, in Britain, but then crashed out of a “brutal” FP1 for Haas in Hungary on his second appearance.
He will replace Romain Grosjean in the VF-17 in Mexico and Magnussen elsewhere. Magnussen will step aside for the Italian in Singapore.
