Formula1.com has now also stated that the two bottom teams will probably not compete this weekend.
They wrote this earlier on the official Formula One website:
Marussia and Caterham look unlikely to compete in this weekend’s 2014 Formula 1 United States Grand Prix, as both teams seek solutions to their ongoing financial issues, the former having gone into administration on Monday.
Administrators for Marussia, FRP Advisory LLP, say the team will continue to operate while they assess the longer-term viability of the company, and that Marussia’s participation in the season’s remaining rounds will depend on the outcome of that process.
Both Marussia and Caterham joined the Formula One grid in 2010, originally as Virgin and Lotus Racing respectively. Both have enjoyed only limited success, with Marussia securing their first world championship points in this year’s Monaco Grand Prix and Caterham yet to score in 93 race outings.
