Lotus team boss Tony Fernandes on Friday refused to confirm speculation Fairuz Fauzy will race a green T127 sometime in 2010.
After the Malaysian 27-year-old tested Heikki Kovalainen's car during initial Friday practice at Sepang, he told BBC radio that Fernandes has hinted he might race later this season.
"I think we don't think too far ahead," Fernandes said when asked by reporters about Fauzy's plans.
"Today (the plan) was to give Fairuz a chance at testing in his home circuit. As for the future we are not sure.
"We will have to wait and see but all I can confirm was that it was for Malaysia only at this point," the Malaysian businessman added.
