Jules Bianchi or Adrian Sutil will partner Paul di Resta at Force India next season after Sebastien Buemi and Jaimie Alguersuari were both ruled out.
The quartet were all linked with the seat that was left vacant following Nico Hulkenberg's departure to Sauber, but former Toro Rosso duo Buemi and Alguersuari are no longer in the running.
According to Swiss newspaper Blick, Buemi has been informed by Force India that he won't be offered the seat while Spaniard Alguersuari is set to move to BMW's DTM team.
That leaves reserve and test driver Bianchi and Sutil, who was a member of the Silverstone-based squad from 2006 until 2011, as the two remaining candidates to partner Scot Di Resta.
Reports suggest Ferrari academy driver Bianchi, who had several Friday practice outings for Force India last season, is the favourite to replace Hulkenberg.
