A county medical examiner says Minnesota Vikings offensive line coach Tony Sparano died of heart disease.
The Hennepin County medical examiner’s office says the 56-year-old Sparano died Sunday of arteriosclerotic heart disease, or hardening of the arteries.
The manner of death is listed as natural.
Sparano began his NFL coaching career in 1999 and had stints as a head coach with the Miami Dolphins and Oakland Raiders. He had been the Vikings’ offensive line coach since 2016.
