EAGAN, Minn. — Tony Sparano, the Minnesota Vikings’ offensive line coach, died Sunday at the age of 56, the team said.

The team announced Sparano’s death in a statement but did not specify the cause of death. Sparano had been the Vikings’ offensive line coach since 2016.

“Tony was a passionate and driven individual who cared deeply about his family, and especially enjoyed spending time with his grandchildren,” the Vikings owners Mark and Zygi Wilf said in the statement. “Tony’s presence within the Vikings organization will be deeply missed.”

Sparano began his N.F.L. coaching career in 1999 and had stints as a head coach with the Miami Dolphins and Oakland Raiders.
