"I would like to apologize to my fans, teammates, coaches, marketing partners and the entire US Soccer and Seattle Reign FC communities for my involvement in a highly unfortunate incident this past weekend," Solo wrote on her Facebook page. "I understand that, as a public figure, I am held to a higher standard of conduct. I take seriously my responsibilities as a role model and sincerely apologize to everyone I have disappointed."
Authorities say Solo was intoxicated early Saturday when she was accused of assaulting her sister and 17-year-old nephew. Police say a family called 911 to say Solo was "going crazy and hitting people."
When police arrived at Solo's sister's Kirkland house, they heard shouting and found Solo's sister and nephew crying and with visible injuries, according to court documents. Police say the nephew's shirt was ripped and his face was red and had marks on it. He also had a bleeding cut on the bottom of his left ear.
Solo was booked into jail for investigation of two counts of fourth-degree domestic violence assault. She has since pleaded not guilty and was released on her own recognizance.
"I love my family dearly," Solo wrote Thursday. "We, like all families, have our challenges but my sincere hope is that we are able to resolve this situation as a family. Adversity has always made us stronger and I know this situation will be no different."
She went on to say she can't comment any further and looks forward to getting back on the field for the Seattle Reign FC and the U.S. Women's National Team.
Solo has been ordered not to have contact with the alleged victims and to refrain from drinking alcohol. Her next court appearance is scheduled for Aug. 11.
