Karun Chandhok has now turned his eye to next month's Belgian Grand Prix as he prepares to sit out a second consecutive F1 race.

The Indian rookie will nonetheless travel to Hungary this week, to reprise the British radio commentary duties he had to settle for at Hockenheim last weekend.

Chandhok was sidelined in Germany due to HRT's Japanese test driver Sakon Yamamoto reportedly having more sponsorship to offer the struggling Spanish team. HRT has now confirmed that Yamamoto will continue to be Bruno Senna's team-mate in Hungary.

"They are going to do what they need to do from their point of view," Chandhok told Reuters. "The long summer break is coming up and we'll have to see what happens for the rest of the season.”

HRT insists that Chandhok is still a team member, but strong rumours indicate that test driver Christian Klien is expecting a race or two later in the season.

A team spokesperson said the driver line-up for Spa Francorchamps and beyond is not finalised.
