Cape Town - US Soccer did not specify the reason for the suspension of goalkeeper Hope Solo which was announced on Wednesday night.
It follows the arrest of her husband, former Seattle Seahawks NFL player Jerramy Stevens, on suspicion of driving under the influence. Solo was in the car when Stevens was pulled over in Manhattan Beach, California, about 1:30 a.m. Monday local time for driving without headlights.
Solo was not arrested or detained. She was in Southern California for training camp with the U.S. national team. The team is preparing for the World Cup starting June.
She was released from camp and will not accompany the team to matches next month in Europe.
"During our current National Team camp, Hope made a poor decision that has resulted in a negative impact on U.S. Soccer and her teammates," coach Jill Ellis said in a statement.
"We feel at this time it is best for her to step away from the team."
Solo was released from camp and will not accompany the team to matches next month in Europe.
It is the latest off-field trouble for Solo. Earlier this month two misdemeanor counts of domestic violence assault charges against he were dismissed. The charges stemmed from an altercation with her half-sister and 17-year-old nephew at a party in Washington last June.
Solo had pleaded not guilty in that case, and she continued to play for the U.S. team and with her National Women's Soccer League team, the Seattle Reign, while awaiting trial.
Her last appearance with the national team was in December, when she started in a scoreless draw against Brazil in the final of the 2014 International Tournament of Brasilia.
Solo will be eligible for reinstatement after the monthlong suspension, pending review and approval by U.S. Soccer and Ellis.
