Chandhok explains absence
Sakon Yamamoto will replace Karun Chandok for the second race in a row as Hispania continue rotating drivers.
Yamamoto replaced Chandhok in Germany and retired with mechanical problems but will replace the Indian driver again in Sunday's Hungarian Grand Prix.
Hispania have four drivers - Yamamoto, Chandhok, Bruno Senna and Christian Klien - under contract and will continue to choose them race-by-race.
Senna, who lost his seat to Yamamoto at Silverstone, also drives in Hungary.
Hispania are known to be struggling financially but it is believed they want to evaluate all their drivers before establishing a line-up for 2011.
It is likely that Klien will be given a run in at least one race as well.
After losing his race seat for the German Grand Prix Chandhok, 26, told the BBC he expected to be back for races later in the season.
"They are going to do what they need to do from their point of view," said Chandhok of the team's position. "What can you do? I just have to keep my chin up.
"The long summer break is coming up and we'll have to see what happens for the rest of the season."
A team spokesperson said a decision on driver line-up for the Belgium Grand Prix on 29 August would be made nearer the time.
