I see on my facebook feed that two reserve teams are being called up, but it doesn't say who - I assume one will be Lotus in place of Level 5. I don't know who the other retiree is, but would they add in another GT car if a prototype drops out?
Both Dyson entries withdrawn, so Status and RLR/Murphy called up. 'Lotus' is the last remaining LMP reserve, there being two GT reserves, both Porsche.
Just realised the cause of my confusion - the 2012 entry list I looked up when I posted this was updated on Friday - so was in effect up to date. I did think it was odd as I thought there were more prototype reserves!
