The former U.S. women's national team goalkeeper made the plea in a Forsyth County courtroom on Monday after cutting a deal with prosecutors, TMZ Sports has confirmed.

In exchange for the guilty plea, we're told the two other charges she was facing in the case -- one count of child abuse and one count of resisting arrest -- were dismissed.

The judge gave Solo a 24-month suspended sentence. She was also ordered to pay fines and fees, and comply with the terms of a substance abuse assessment.

As part of the sentence, we're told Solo has already completed a 30-day, in-patient rehabilitation program at the Hope Valley treatment facility in North Carolina earlier this summer.

Following the plea in court, Solo released a lengthy statement on her social media page ... admitting "I underestimated what a destructive part of my life alcohol had become."

"The upside of making a mistake this big is that hard lessons are learned quickly," the 40-year-old added. "Learning these lessons has been difficult, and at times, very painful."

"I continue to be a student of the greatest school called life and I will continue to learn and grow from these experiences. I will continue to gain empathy, knowledge, and stories to share."

"I consider this a gift to pass it on to others because pain shared is pain lessened."

We broke the story ... Solo was arrested back on March 31 after cops say they found her passed out behind the wheel of her car in a Walmart parking lot while her two children were in the vehicle with her. Cops say during the stop, she displayed signs of impairment and reeked of booze. They added that she had refused sobriety tests at the scene.
