United States captain Todd Clever escaped suspension after being charged with a dangerous tackle and shoulder charge during the Eagles' 13-6 win over Russia in New Plymouth on Thursday.
The openside flanker admitted to the charge of a dangerous tackle, but the judicial officer deemed the incident to be at the lower end of the scale, World Cup officials said in a statement.
The United States have two Pool C games remaining, Australia in Wellington on Sept. 23 and Italy in Nelson on Sept. 27.
