Would be shame to go from Raikkonen to Valsecchi from Lotus' point of view, quite the difference in results I'd imagine.
Think Lotus still have d'Ambrosio on their books too.
...and there's always Nick Heidfeld... he's steady at least
Don't think it would, lotus aren't going to move championship positions and they have to pay him per point
If this really is a back injury thing then next year might not be so good for ferrari
