Hispania Racing Team on Tuesday did not reveal the identity of its race drivers for this weekend's Japanese grand prix.
Sakon Yamamoto, who earlier this year replaced team regular Karun Chandhok, sat out the recent Singapore round with what the struggling Spanish outfit said was food poisoning.
Reserve driver Christian Klien stepped into the cockpit, impressing with his pace despite admitting the Singapore outing was a "one-off".
The Austrian's Singapore GP teammate Bruno Senna has also sat out a race this year - July's British grand prix - amid speculation HRT is selecting its drivers based on their current financial endowments.
The uncertainty about HRT's Suzuka lineup was triggered on Tuesday, when the team's traditional pre-event press release did not mention any of the team's contracted drivers Yamamoto, Klien, Senna or Chandhok.
Asked to nominate HRT's race lineup for Suzuka, Kolles told Germany's motorsport-total.com on Tuesday: "We're planning with our regular drivers.
"They are Senna and Yamamoto," he said.
However, he declined to guarantee that will be HRT's lineup in Japan this weekend.
"You never know what's going to happen," said Kolles. "What happens if someone breaks a leg?"
