Mercury Morris, Miami Dolphins legend, dies at 77

Mercury Morris, a key player in the Miami Dolphins' undefeated 1972 Super Bowl team, has died at the age of 77.

Mercury Morris, the former Miami Dolphins running back and key member of their undefeated 1972 Super Bowl team, passed away at the age of 77, according to his family. The Miami Herald confirmed Morris’ death through the Dolphins. Morris’ son, GhostWridah, shared the news on X (formerly Twitter), describing his father as a "legendary Miami Dolphins running back" whose "electrifying speed and dynamic play" made him a cornerstone of the team's historic season.

Morris, a three-time Pro Bowler and two-time Super Bowl champion, helped lead the Dolphins to a 14-0 regular-season record in 1972, rushing for 1,000 yards and 12 touchdowns. His contributions, alongside teammates Larry Csonka and Jim Kiick, created what became known as the “perfect backfield.” Reflecting on Morris’ passing, Csonka wrote on X, “It’s a very sad day for me and our Dolphin family.”

After playing for the Dolphins from 1969-1975, Morris was traded to the San Diego Chargers in 1976, where he played one season before retiring. Morris later faced legal challenges, including a drug trafficking conviction that was overturned after serving more than three years in prison. He spent his post-football years as a motivational speaker, discussing his time in prison and his life after football.

Morris is survived by five children and three siblings.
