Vitaly Petrov is in talks about becoming Caterham's third and reserve driver in 2012.
Finland's Turun Sanomat newspaper reports that the Russian's manager, Oksana Kosachenko, visited the former Team Lotus outfit's Hingham (UK) headquarters last week.
27-year-old Petrov has been dropped by Renault (now Lotus) after his first two seasons in the sport.
It has been rumoured that the race seat alongside Heikki Kovalainen at Caterham might be up for grabs for 2012, but Turun Sanomat said it is now likely that Jarno Trulli's contract will be honoured.
The report said Petrov would be the third driver in 2012 before coming into consideration for a race seat next season.
Caterham's third driver in 2011 was Indian Karun Chandhok, who is now looking for a similar role elsewhere to split his time between F1 and the FIA's new world endurance sports car championship this year.
