Wieber finished fourth during qualifying Sunday, but will miss a shot at Olympic gold because international rules only allow two competitors per country in the finals.
Teammates Aly Raisman and Gabby Douglas finished ahead of Wieber, leaving the 17-year-old on the outside of a major competition final for the first time as an elite gymnast.
John Geddert, who has coached Wieber during her entire career, called the rule ridiculous, saying it penalizes countries that have deep rosters.
Wieber posted on her Facebook page that it was "hard to explain these feelings" but is honored to be on Team USA.
