Motor racing-Caterham and Marussia to miss next races; Ecclestone

(Reuters) - The struggling Caterham and Marussia Formula One teams will both miss next week's U.S. Grand Prix in Austin, Texas, the sport's commercial supremo Bernie Ecclestone told Reuters on Saturday.

"Neither of those two teams are going to go to America," said the 83-year-old.

Their absence will increase concern in the sport, whose smaller outfits have been saying for some time that they risk going out of business unless costs are slashed, even though Ecclestone has said he would be happy with 10 teams.

Caterham went into administration on Friday while Russian-registered Marussia are also struggling financially and are still reeling from French driver Jules Bianchi's serious accident in Japan three weeks ago.
