After seeing his FP1 outing at Monza washed away, Ferrari reserve driver Antonio Giovinazzi will replace Kevin Magnussen for FP1 at Singapore next weekend.
Giovinazzi was given six FP1 outings starting from Silverstone and Monza was supposed to be the third in this run for Haas. However, the rain forced Haas to give priority to Magnussen again with more rain to come for qualifying on Saturday.
But Giovinazzi has not lost out, with Magnussen now stepping aside at the Marina Bay Circuit to give the young Italian more time in a Formula 1 car.
Giovinazzi, alongside F2 leader Charles Leclerc, are both looking to get a full-time spot on the Formula 1 grid and continue on their path to becoming Ferrari drivers in the future.
But Maurizio Arrivabene has warned they both have plenty to prove if they are achieve their dream of driving for the Scuderia.
"Talking about the young drivers, they are growing," said Arrivabene.
"Our objective is of course to grow up young drivers and maybe to see them in the future with us.This is the final goal.
'But, before that, they need to demonstrate in Formula 1 that they deserve it."
Giovinazzi has more FP1 outings to come in Malaysia, Mexico, Brazil and Abu Dhabi, while Leclerc is widely expected to join Sauber next season with Mercedes-backed Pascal Wehrlein making way.
