Stanford announced the news of Garza’s unexpected death. The cause of death was not immediately known.
Garza was assistant professor of orthopaedic surgery and emergency medicine at the Stanford School of Medicine. His primary research focused on the prevention of traumatic brain injury in athletes.
The 49ers confirmed news of Garza’s death with a statement late Wednesday:
“The 49ers organization has been informed of a tragedy. We were saddened to learn Dr. Dan Garza died unexpectedly Tuesday. Our sincerest thoughts and prayers are with his family and friends during this trying time."
Garza attended all 49ers games and was the person responsible for diagnosing concussions on the sideline during games.
"Dan Garza was very dedicated to sports medicine, to teaching human physiology and to his research to improve recovery and treatment outcomes for athletes," said William Maloney, professor and chair of the department of orthopaedic surgery. "He was persistent in his desire to find solutions to one of the most concerning areas in our field, the prevention of concussions and head trauma. We are saddened by his loss and the loss to our profession."
Garza conducted extensive studies on the risk of concussions by fitting athletes in football, soccer, lacrosse and field hockey with mouthpieces to measure the impact of their collisions. He completed his medical internship and residency at Stanford Hospital and began working with the 49ers in 2007, according to Stanford.
