Force India waiting on Ferrari line-up
Force India won't confirm their 2015 line-up until after Ferrari as uncertainty over the latter's drivers could yet affect Nico Hulkenberg.
Hulkenberg has, for several seasons, been linked to Ferrari, however, as yet nothing has materialized.
Last season many thought the German would be heading to Italy after spending a year with Sauber but Ferrari instead opted to partner Kimi Raikkonen with Fernando Alonso.
The team is set for another change next season as Alonso is leaving and is expected to be replaced by Red Bull's Sebastian Vettel.
There are also still questions about whether Raikkonen is definitely staying or if a second seat will open up.
And until Ferrari confirm their full line-up, other teams including Force India are unable to lock down their drivers.
"There are always elements in contracts that just have to be finalized out," deputy team principal Bob Fernley told Crash.net.
"Those will be done over the next week or two, but fundamentally it's a done deal for going forward.
"Maybe not by Austin, we're not always the quickest to announce our driver line-ups!"
Pressed as to whether Ferrari's delay in announcing their line-up was impacting Hulkenberg's confirmation, he said: "There's an element of that, yes, because obviously that's part of the contracts we have with Nico. So we have to take that in to consideration.
"Those are the elements that delay things slightly and then obviously you finish them off."
