Bruno Senna, Heikki Kovalainen and Vitaly Petrov will have to wait to learn their fates as Caterham will not make an announcement in the 'foreseeable future'.
With only Charles Pic confirmed for this season's Championship, Caterham is one of just two teams with a seat still available.
And although 2012 drivers Kovalainen and Petrov are keen to remain with the team, Senna is believed to be leading the chase.
However, for now all three still stand a chance as Caterham failed to deliver the announcement that rumours claimed would come this past week.
"Caterham have said nothing is being announced in the foreseeable future as all options are still being considered," Finnish MTV3 commentator Oskari Saari said.
