Caterham not ready to complete 2013 lineup

Caterham is not yet ready to announce its full 2013 driver lineup.

The team has already filled one of this year’s race seats with 2012 Marussia rookie and Frenchman Charles Pic.

Rumours on Thursday suggested an announcement about his teammate was imminent, with Bruno Senna and Vitaly Petrov thought to be the front-runners.

Russian Petrov’s teammate last year was Finn Heikki Kovalainen.

As for Thursday’s rumblings about an imminent announcement, Finnish MTV3 commentator Oskari Saari said: "It was just a rumour then.

"Caterham says nothing is being announced in the foreseeable future as all options are still being explored."
