Haas say they have yet to make a decision whether Russian driver Nikita Mazepin will continue driving for the team this year.
The American outfit removed its sponsorship from Russian company Uralkali late Thursday and is running plain white cars on the final day of F1 pre-season testing in Barcelona. Haas not only receives significant funding from Russian company Uralkali but also fields a car for Russian driver Mazepin
Fertiliser company Uralkali counts Dmitry Mazepin, the father of Haas' Russian driver Nikita Mazepin, as one of its major shareholders.
"Yeah, it needs to be resolved," Haas team principal Guenther Steiner told reporters when asked about Mazepin's future.
"As I said before, not everything depends from us here. There is more than the F1 team involved, there are governments involved, so I have no idea what is coming from that side."
He added to Sky Sports News: "At the moment we want to continue but there is external things that could happen which I'm not in control of. Therefore saying what exactly could happen in the coming weeks, months... but at the moment he is planned to be in Bahrain.
"If circumstance comes in place, we have to obey to them. I don't want to get ahead of myself, they first have to come and then we react."
