Dan Doornink, the former Seattle Seahawks running back and respected Washington physician, died on Saturday, October 31, 2026, at the age of 70, following a prolonged battle with two rare autoimmune diseases. His family confirmed that ongoing health complications contributed to his death, bringing renewed attention to the remarkable life of a man who balanced professional football with a career in medicine. Known affectionately as “Dr. Dan” and “Mr. Third Down,” Doornink leaves behind a lasting legacy in both sports and healthcare.
Cause of Death
Dan Doornink’s cause of death was linked to complications from two rare, chronic autoimmune diseases, according to a statement released by his family.
The former NFL player’s health had been affected by these conditions for an extended period.
Although his family acknowledged his prolonged medical struggles, the initial announcement did not publicly identify the two diseases by name.
Consequently, reports assigning a specific diagnosis to either condition should be treated cautiously unless supported by additional family statements or reliable medical information.
His death marked the end of a difficult health journey that had already included a life-threatening illness several years earlier.
Family Statement
Doornink’s family announced his passing with deep sadness, describing the emotional impact of losing a husband, father, grandfather, and respected member of the community.
Their statement acknowledged the challenges he faced while living with chronic autoimmune conditions.
The announcement also reflected the importance of family throughout his life.
Despite his achievements in professional football and medicine, Doornink remained closely connected to his loved ones and his hometown.
His passing prompted tributes from former teammates, football supporters, and people who remembered him through his medical practice.
Previous Health Battle
Doornink had previously experienced a serious medical emergency after contracting COVID-19 in 2021.
His condition became particularly dangerous because of an underlying autoimmune blood disorder.
Reports from that period described a dramatic reduction in his blood platelet levels, creating potentially life-threatening complications.
Platelets are essential for normal blood clotting, and dangerously low levels can increase the risk of bleeding.
The combination of COVID-19 and his existing medical condition made his recovery especially challenging.
His family later described his survival as extraordinary.
Although he recovered from that episode, he continued dealing with significant health concerns in the years that followed.
Who Was Dan Doornink?
Dan Doornink was an American professional football player and internal medicine physician whose unusual career brought him recognition far beyond the NFL.
Born in Yakima, Washington, he developed into an accomplished athlete before attending Washington State University.
He became a standout running back for the Washington State Cougars, earning recognition for his versatility and determination.
His college performances helped establish the foundation for his professional football career.
However, Doornink also maintained a strong interest in academics and medicine.
That combination eventually made him one of the NFL’s most distinctive personalities.
NFL Career
Doornink played eight seasons in the National Football League, beginning with the New York Giants before joining the Seattle Seahawks.
He spent seven seasons with Seattle, becoming a dependable contributor to the team’s offense.
Rather than relying solely on spectacular individual performances, he built his reputation through consistency, intelligence, and versatility.
He was especially effective in situations requiring short-yardage gains or reliable execution.
His ability to contribute in important moments earned him the nickname “Mr. Third Down.”
For longtime Seahawks fans, Doornink became associated with an important period in the franchise’s early history.
Famous Playoff Game
One of Doornink’s most memorable performances came during the 1984 AFC wild-card playoff game against the Los Angeles Raiders.
The Seahawks entered the matchup facing a formidable opponent, but Doornink delivered a standout rushing performance.
He gained 126 rushing yards, helping Seattle secure a memorable postseason victory.
His contribution became a defining moment in his football career.
The performance demonstrated his ability to step forward when the team needed him most.
Decades later, the game remained a significant part of his legacy among Seahawks supporters.
Why Dr. Dan?
Doornink’s nickname “Dr. Dan” reflected an achievement rarely associated with professional football players.
While competing in the NFL, he also pursued medical education at the University of Washington.
Balancing medical school with the physical demands of professional football required considerable discipline.
NFL players must devote substantial time to training, travel, game preparation, and recovery.
Medical education involves an equally demanding schedule of study, examinations, and clinical training.
Doornink’s ability to pursue both careers made him an unusual figure in professional sports.
His commitment to medicine continued long after his playing days ended.
Medical Career
After retiring from football in 1986, Doornink concentrated on his career as an internal medicine physician.
He returned to Yakima, Washington, where he practiced medicine for more than three decades.
Internal medicine physicians specialize in diagnosing, treating, and managing health conditions affecting adults.
Their work frequently involves long-term relationships with patients managing complex medical needs.
Doornink became a respected member of the local healthcare community.
For many people in Yakima, he was known primarily as their doctor rather than as a former professional athlete.
His medical career demonstrated that his dedication to helping others extended beyond the football field.
Washington State Legacy
Doornink maintained a strong connection with Washington State University, where his athletic career had first attracted widespread attention.
His achievements as a Cougar helped establish his reputation before he entered the NFL.
He was later recognized among the university’s notable former athletes.
His story also represented an example of how collegiate athletics and academic achievement can complement one another.
For Washington State supporters, Doornink’s success in football and medicine remained a source of pride.
His passing brought renewed appreciation for his contributions to the university and the broader Washington community.
Wife and Children
Dan Doornink is survived by his wife, Sharon, their four children, and five grandchildren.
His family remained an important part of his life throughout his football career, medical practice, and later health challenges.
Although his professional accomplishments received widespread attention, he maintained close personal connections away from public life.
The family’s announcement of his death highlighted the personal loss behind the passing of a familiar sports figure.
For his loved ones, he was more than a former Seahawks player or respected physician.
He was a husband, father, and grandfather whose presence shaped their lives.
