Haas team principal Guenther Steiner believes it is now too late for F1 to add replacement grands prix should more fall by the wayside this season.
In just 101 days, the curtain will fall on the 2021 F1 campaign in Abu Dhabi but there remain concerns over a number of races, specifically those in South America.
“If there are changes, I think there will be more cancellations and not any changes anymore because we are just running out of weekends at the moment," said Steiner.
"There is not a lot you can do anymore.
“If something will happen, depending always on the corona[virus], at the moment FOM and Stefano [Domenicali, F1 CEO] are pushing hard to get this calendar to the end like it is now but you never know."
“As we saw last weekend, we don’t have nature under control so if the pandemic hits hard in one of the countries we are going to, I think the only option is to cancel the event," added Steiner.
“I don’t think there is a big option to change it to another place because there is just not enough time.
“If you think, in a little bit more than three months the season is over.”
