The Japanese, reportedly with $5 million in sponsorship to pay to the struggling Spanish team in 2010, raced initially in Bruno Senna's cockpit at the recent British grand prix.

He then replaced Karun Chandhok in Germany, but the Indian rookie - whose new sponsor Japyee was on the Cosworth-powered F110 at Hockenheim - said it is possible he will be back in the car this weekend in Hungary.

But in a media statement, Hispania Racing announced its Hungaroring lineup as Yamamoto, 28, alongside Senna.

"I can't wait to go back to the Hungaroring as I know the circuit already very well from my formula one races with Super Aguri, Spyker and with ART in the GP2 series," said Yamamoto.
