The Louisiana State University community and the tight-knit world of collegiate dance are rallying around Sianna “Sisi” Armstrong, a beloved member of the LSU Tiger Girls, following a devastating car accident. On Tuesday, February 17, 2026, Sianna was traveling back to Baton Rouge after visiting her family to celebrate her upcoming 20th birthday during the Mardi Gras break. The accident occurred on Interstate 20 in Greenwood, near Shreveport. While Sianna was wearing her seatbelt, the mechanical failure of her vehicle’s airbags to deploy resulted in severe facial trauma and multiple fractures, turning a celebratory weekend into a fight for recovery.
A Marathon of Recovery: Strength in the Face of Adversity
Sianna’s journey over the past several weeks has been defined by incredible grit and the support of elite medical teams. Following the initial crash, she was transported to a trauma unit in Shreveport, where she has undergone extensive procedures to begin the long process of reconstruction.
* Initial Surgery: On February 20, Sianna underwent an intensive 15-hour surgery to repair facial fractures and reconstruct her airway.
* Continued Progress: As of early March, she continues to breathe with the help of a tracheostomy tube and has her jaw wired shut to allow her injuries to heal.
* Recent Milestone: On Friday, March 6, 2026, Sianna underwent a secondary critical surgery to receive an orbital floor implant in her right eye—a major step in restoring her comfort and quality of life.
The Spirit of the Tiger Girls: “She Will Dance Again”
The LSU Tiger Girls and Coach Kandace Hale have described Sisi as a “bright, joyful light” whose energy and determination are the heart of their team. Her mother and stepfather, Sasha and Chase Marrier, have remained steadfast by her side, sharing updates that highlight Sianna’s remarkable spirit. Despite the long road ahead, her family remains resolute, stating firmly that “She will dance again.” The outpouring of support through a community GoFundMe has nearly reached its goal, a testament to the lives Sisi has touched through her kindness and talent. We hold Sianna and the entire Armstrong-Marrier family in our deepest thoughts as she continues her brave walk toward the stage once more.
