USWNT star forward Mallory Swanson suffers torn patella tendon in left knee in friendly vs. Ireland

Swanson, 24, hurt her knee Saturday in the first half of the eventual 2-0 U.S. victory in Austin, Texas. She collided with an Irish player and fell to the ground, yelling out in pain as teammate Rose Lavelle knelt beside her to comfort her. Swanson, who had scored in all five of the USWNT's games so far this year, was put on a stretcher and while being carted off the field, she held up her hands in the shape of a heart to show love to the crowd.
