Formula1.com: Marussia and Caterham set to miss Austin round

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.

Juan Pablo Montoya on the David Letterman Show

This was in 2006 if I remember correctly. They were talking about the US GP on the show. That was actually his last race in Formula One but he didn't know that yet.

Montoya crashed into his teammate Kimi Räikkönen after the first corner and they both retired. Montoya had not shown the same pace as Räikkönen in 2005-2006 and the crash was just the last straw for the team boss Ron Dennis.

Montoya got replaced by Pedro de la Rosa right after the US Grand Prix and he got a podium in the next race. Pedro de la Rosa became the testdriver again after the 2006 season when Lewis Hamilton joined the team from the GP2-series.
