Tony Sparano, a two-time NFL head coach who had been the Vikings offensive line coach since 2016, died Sunday morning at the age of 56, the team said.
"Our hearts go out to Jeanette and the entire Sparano family as we all mourn the loss of Tony," Vikings owners Mark and Zygi Wilf said in a statement. "Tony was a passionate and driven individual who cared deeply about his family, and especially enjoyed spending time with his grandchildren.
"Tony's presence within the Vikings organization will be deeply missed. We are only thinking of Tony's family during this incredibly difficult time. We ask that the entire NFL and Vikings family keep the Sparanos in their thoughts."
Emergency personnel were notified shortly after 8 a.m. Sunday of Sparano's need for medical attention.
Dispatch audio revealed that a female was performing cardiopulmonary resuscitation on Sparano at the home in the Bearpath gated community in Eden Prairie.
ESPN reported that Sparano recently had complained of chest pains and went to the hospital Thursday, before being released Friday following a round of tests. According to ESPN, Sparano's wife, Jeanette, found him unconscious in the couple's kitchen when both were about to leave for church Sunday morning.
The news stunned the Vikings organization two days before rookies were scheduled to report to training camp at the team's new practice facility in Eagan. Sparano, known around the league for his no-nonsense approach and a gruff demeanor that belied a gregarious personality, was set to be back in the building Monday as coaches returned to work.
"I am at a loss for words with Tony's sudden passing," General Manager Rick Spielman said in a statement. "Tony loved the game of football and his players. More importantly, he was a strong man of faith who treasured his family. My heart is with the Sparanos today. As an organization we will support them in whatever ways we can."
