Christian Klien will be back in action for the HRT team at this weekend's Brazilian grand prix.

The Austrian also replaced Japanese Sakon Yamamoto in Singapore due to food poisoning, but no reason has been given for the change of drivers ahead of the Interlagos event.

"I am very happy to get a second opportunity to do another grand prix here after Singapore and I hope that we are doing a good weekend with positive results," said Klien, 27.

He has raced at Interlagos twice before, most recently in 2005 with Red Bull.

The Austrian newspaper Kleine Zeitung said recently Klien might return to the Cosworth-powered F110 cockpit in Brazil or Abu Dhabi in a last-ditch effort to help HRT beat Lotus to tenth place in the constructors' championship.
