Olivia Moultrie's breakout season in Portland has come to an abrupt halt. The 20-year-old Thorns midfielder has a torn right ACL and will miss the remainder of the NWSL season after sustaining the knee injury during a training session last week, the club confirmed. It's a gutting turn for a player who has spent her entire career shattering age-based records, and one that now threatens her availability for next year's FIFA Women's World Cup in Brazil.
According to Reuters, the Portland Thorns placed Moultrie on the season-ending injury list after the club confirmed she sustained the knee injury during training last week. Thorns general manager Jeff Agoos said Moultrie is “one of the most driven players he has been around,” and pledged that the club will provide her full support and club resources during her recovery, per the same report. Moultrie has started 15 matches and made 16 appearances this season for Portland, recording five goals and five assists, and her final game came against Denver Summit FC at Centennial Stadium on July 18.
A Season Cut Short at a Pivotal Moment
The timing stings. Portland currently sits in fifth place in the NWSL standings after 19 matches, and Moultrie was a central piece of that playoff push before the injury. She has also become a fixture for the U.S. Women's National Team, making 18 appearances and scoring five goals since her 2023 debut, and she was part of the USWNT squads that won the 2024 SheBelieves Cup, the 2024 CONCACAF W Gold Cup, and the 2026 SheBelieves Cup.
ACL reconstruction requires a long recovery, and the timeline could not be more unforgiving. Moultrie will miss the 2026 CONCACAF W Championship, set for November 27 through December 5 in Texas, which serves as North America's qualifying tournament for four direct slots in the 2027 FIFA Women's World Cup, according to FIFA. That leaves her potentially missing the World Cup itself, which begins next June in Brazil — the first Women's World Cup ever hosted in South America. Her August injury leaves roughly a 10-month rehabilitation window to regain fitness and contend for a roster spot before the tournament kicks off.
From Teenage Trailblazer to Record-Setter
Few players have compressed as much history into so few years. Moultrie filed a landmark federal antitrust lawsuit against the NWSL's age rule in May 2021 at just 15 years old, a case that resulted in a court injunction and a July 2021 settlement eliminating the league's 18-year-old age restriction, as detailed by Business Insider. That legal victory opened the door for her own professional career and for every underage player who has signed since.
She wasted little time cashing in on the opportunity she created. In June 2022, at 16, Moultrie became the youngest goal scorer in NWSL history, scoring in the 74th minute of a 4-0 Thorns win over the Houston Dash, surpassing Ellie Carpenter's previous mark, as The Guardian reported at the time. She was named the 2023 U.S. Soccer Young Female Player of the Year, and during a CONCACAF W Gold Cup match against the Dominican Republic in February 2024, an 18-year-old Moultrie scored twice — a feat only Mia Hamm and Cindy Parlow Cone had accomplished at a younger age for the USWNT, per the Los Angeles Times.
Her scoring pace kept climbing right up until the injury. In September 2025, three days before turning 20, she scored her 14th regular-season goal on a 20-yard direct free kick against Chicago Stars FC, surpassing Jaedyn Shaw to become the highest-scoring teenager in NWSL history, according to Field Level Media. Then in May 2026, at age 20, Moultrie became the youngest player in league history to reach 100 regular-season appearances, marking the milestone by scoring and assisting in a match against the Stars — achieving the feat faster than any other player in NWSL history.
A Wider Pattern of Knee Injuries in Women's Soccer
Moultrie's tear adds another name to a growing list of serious knee injuries among elite women's soccer players, an issue the sport's own institutions have begun to formally study. In April 2026, the NWSL and NWSL Players Association joined “Project ACL,” a three-year global initiative with England's Women's Super League, FIFPRO, and Nike aimed at researching the environmental, workload, and schedule factors behind knee injuries in the women's game, according to FIFPRO. Existing sports-science research remains thin on the subject — only about 8 percent of it focuses on women, per the same initiative.
The medical stakes behind that research effort are stark. A review published in Science Progress in April 2026 found that female soccer players sustain ACL injuries at rates two to nine times higher than male players, with roughly 90 percent occurring without physical contact, typically during cutting, decelerating, or landing motions. Researchers point to intrinsic factors such as dynamic knee valgus, quadriceps dominance, and joint laxity as contributors to that disparity.
Recovering Close to Home
Moultrie will do her rehabilitation work near the Thorns' newly consolidated home base. Parent company RAJ Sports moved operations near the $150 million, 12-acre Kaiser Permanente Performance Center in Hillsboro this past May, a complex that includes a 63,000-square-foot training building and dedicated sports-medicine and recovery facilities, as Hoodline previously reported. It's the same broader Portland sports landscape that has recently seen other high-profile athletes sidelined by knee injuries, including Portland Fire guard Sarah Ashlee Barker and Gotham FC's Emily Sonnett, who also went down with season-ending knee surgery during a game in Portland.
For now, Moultrie's season is over, and her path back to the national team picture runs through a demanding recovery clock. Whether that 10-month window is enough to get the record-setting midfielder ready for Brazil remains an open question the Thorns and the USWNT will be watching closely in the months ahead.
