The Portland Thorns have signed midfielder Olivia Moultrie, 15, after a protracted legal battle with the National Women's Soccer League.
The NWSL attempted to prevent Moultrie from signing a professional deal, citing the league's minimum age of 18.
After suing the league, Moultrie and her legal team were granted a preliminary injunction earlier this month that allowed her to sign a three-year deal with the Thorns.
