Overview

• Greener suffered quadriplegia in 2018 after instructor Francisco Iturralde applied his full body weight to his neck during a sparring session.
• A San Diego jury awarded Greener $46 million in 2023 and post-judgment interest raised the award to $56 million.
• Iturralde, a second-degree black belt nicknamed “Sinistro” for his aggressive grappling style, appealed but saw the judgment upheld by California’s highest court.
• Following the injury, Greener endured multiple strokes and spent several months hospitalized just weeks before his college graduation.
• Greener has since become a mountain climber and motivational speaker advocating for increased safety and accountability in sports instruction.
