Esteban Gutierrez has announced that he will leave Haas at the end of the season, seemingly paving the way for Kevin Magnussen to join the American manufacturer.
Gutierrez has endured a disappointing maiden campaign for the Formula One newcomers, failing to score a solitary point.
The Mexican driver on Friday revealed that he not be taking a seat with Haas in 2017 and will give details of his next move before long.
"Dear Friends, I want to share with you that I will no longer be with Haas F1 Team for the next season," Gutierrez posted on Facebook.
"I want to thank all the team and staff, especially Gene Haas for this opportunity to work with them. I wish them all the best. There are two races left, which I intend to enjoy to the fullest and as always, I'll give my best.
"Special thanks to all my fans and supporters, you will always have a place in my heart.
"I hope to shortly share my plans for the future. Warm regards! #EG21"
All the indications are that Magnussen and Romain Grosjean will be team-mates at Haas next year.
Magnussen took a swipe at Renault and revealed that it was his choice to move on after the French manufacturer failed to offer him an acceptable new contract.
Renault this week announced that Jolyon Palmer had been retained for next year after Nico Hulkenberg was recruited from Force India.
"It was my decision - I had an offer but not a good enough offer that I could take it," Magnussen said.
"If they'd committed to a longer contract I would probably have looked at that much more seriously.
"It was more the feeling of them not committing, taking so long and offering to so many drivers - I think at one point the Pope had an offer. It was a bit messy, so it was better for me to leave."
"It really is a lot about the feeling I had with the management here. More openness would have been good.
"Sometimes it was a little bit difficult to know who was actually in charge here, who was making the decisions, but that's over now, it doesn't matter. It's in the past.
"If I had felt more commitment and decisiveness then it would maybe have been different, but I'm happy with the way it turned out."
