Vitantonio Liuzzi has acknowledged that he is looking into an "uncertain" future despite possessing a contract for 2012.
The 30-year-old joined HRT last year before the Spanish team was sold by Jose Ramon Carabante to its current owners, Thesan Capital, and boss Colin Kolles was replaced by the former Minardi driver Luis Perez-Sala.
Sala said before Christmas that HRT is in "advanced talks with several drivers" as the team considers the identity of Pedro de la Rosa's 2012 teammate.
Liuzzi, however, insisted recently that he inked a "long term" contract in early 2011.
"It would have made no sense to sign with a team at this level on just a one year contract; you have to make it a project for the future", he told Australian Motorsport News.
He now acknowledges that his future is in doubt.
"I have a contract to race next season with HRT but the agreement was concluded with the previous owner and now the future is uncertain," Liuzzi conceded to Brazil's Totalrace.
