Three Formula 1 teams 'plotting United States Grand Prix boycott'

Three of Formula 1's smallest constructors have reportedly discussed the idea of boycotting this weekend's United States Grand Prix in protest at the financial collapse of two teams over the past week.

According to The Telegraph, Lotus, Force India and Sauber are all thought to be considering a plan to sit out Sunday's race at the Circuit of the Americas in Texas.

The alleged boycott plan comes after Marussia and Caterham both entered administration this week.

It is thought that the three teams are furious that the F1 backmarkers were allowed to go out of business by the sport's authorities and could now facilitate a similar walkout to that seen at the 2005 US GP in Indianapolis, which saw just six cars start the race.

Formula 1 ringmaster Bernie Ecclestone has also voiced concerns that just 14 cars could line up on the grid from next season, due to the current financial crisis.
