Esteban Gutierrez says that there are other F1 alternatives currently under review should Haas decide not to include him in its yet to be announced 2017 line-up.
The US squad is expected to retain the services of Romain Grosjean but it is believed that the Mexican may be forced to relinquish his race seat.
While Grosjean has scored on his own all of Haas' 28 championship points this season, his team mate has finished 11th - just outside the points - on five occasions.
"There are alternatives we are considering," Gutierrez told Motorsport.com.
"In the coming weeks we will make a decision. There are other interesting opportunities that we cannot put aside."
Given the limited number of race opportunities left on the 2017 grid, Gutierrez's considered alternatives are more likely linked to a reserve driver role rather than a race seat.
The 25-year-old also retains an association with Haas' technical partner Ferrari, but his priority still lies with the US outfit.
"Yes, I would continue with them," he concluded.
