Bob Heinz, a former NFL defensive tackle who was on the Miami Dolphins' 1972 undefeated team, died on Saturday, October 31, 2026. Heinz passed away from natural causes at age 79 at his home in Fresno, California.
In a statement on social media, the Dolphins said, "We are saddened to learn of the passing of a former Dolphins defensive tackle, who played for Miami from 1969-77." Bob was part of the Dolphins' 1972 Perfect Team, a two-time Super Bowl champion, and a key part of Miami's legendary 'No-Name Defense'.
The Milwaukee native, Heinz started eight games and appeared in 11 during that 1972 perfect season, playing right defensive tackle on a standout defensive line. Heinz played at the collegiate level for the University of the Pacific, where he married Carol Covington, his wife of 56 years.
The Dolphins picked Heinz in the second round of the 1969 NFL/AFL draft, and he appeared in all 14 games, with one start as a rookie. He played eight seasons in Miami, appearing in 109 games and starting 55.
He started every game of the 1973 season and all but one game in 1974 before missing the 1975 season due to an injury. Heinz played eight seasons for the Miami Dolphins, appearing in 109 games and winning two Super Bowls for the franchise during the 1972 and 1973 seasons.
He appeared in his last NFL season for Washington, where Heinz played two games as a reserve, finishing his career with 9 sacks. After hanging up his cleats, Heinz worked as an advertising executive in Palo Alto and Menlo Park, California, before moving to Fresno.
Heinz is survived by his wife, Carol; his three children, Julie, Joe, and John; and two grandchildren. His legacy remains etched in the history of American football as a cornerstone of the only team to complete an entire NFL season without a single loss or tie.
The sports community continues to pay tribute to his contributions, remembering him as a dedicated athlete and a humble individual off the field. Funeral arrangements are expected to be announced by the family in the coming days as fans and former teammates share their condolences.
