Potential boycott bubbling at US Grand Prix

AUSTIN, Texas (AP) One of the top racing officials at Sahara Force India says up to three teams are considering a boycott or pulling out after one lap of Sunday's U.S. Grand Prix to protest the financial gap behind the sport's richest teams in Formula One.

Bob Fernley, deputy team principal for Sahara Force India said Saturday it would a difficult decision left up to the team owners. Fernley said either scenario is ''not off the table.''

Fernley identified the other two teams as Sauber and Lotus. All three are facing financial struggles.

Lotus chairman Gerard Lopez said he was unware of any collaboration and would be surprised if the teams didn't race. Sauber team principal Monisha Kaltenborn declined comment.

Two other teams, Marussia and Caterham, are in bankruptcy and won't race Sunday.
