Minnesota Vikings offensive line coach Tony Sparano has died unexpectedly at the age of 56, the team announced Sunday afternoon.
"I am at a loss for words with Tony's sudden passing. 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," Vikings general manager Rick Spielman said in a statement.
Sparano had complained about chest pains and went to the hospital Thursday, a source told ESPN's Chris Mortensen. Sparano underwent tests and was released Friday. The source said Sparano's wife found him unconscious Sunday morning as they prepared to leave for church but could not revive him.
