Eugene “Mercury” Morris, a two-time Super Bowl winner with the Miami Dolphins and the linchpin of the team’s perfect 1972 season, has died, his son Troy-Jeffrey Morris announced on behalf of the family on social media on Sunday. Mercury Morris was 77 years old.

“His talent and passion left an indelible mark on the sport, and his three-time Pro Bowl selection only cemented his place among football’s greats,” the statement said.

“Off the field, Mercury was a devoted father, a loving brother, a loyal friend and a pillar of the community. His presence extended far beyond football as he touched the lives of many during his time in Miami.”

Known for his speed and dynamic running game, Morris achieved career-best performances with 1,000 yards and 12 touchdowns in the historic 1972 Super Bowl season, in which he won the Super Bowl undefeated.

Morris and Hall of Fame fullback Larry Csonka, who rushed for 1,117 yards, became the first two running backs from the same team in NFL history to rush for 1,000 yards in the same season.

The following season, Morris ran for 954 yards and 10 touchdowns, helping Miami win its second consecutive Super Bowl title.

Morris and other members of the 1972 team popped champagne to celebrate the last undefeated team of the season.

“Morris left a lasting impression with his dynamic play, personality and record-setting performances,” the Dolphins said in a statement. “He loved the Dolphins, the fans and the South Florida community and will forever be remembered as one of the greatest players to ever wear the teal and orange jersey.”

“Our thoughts are with his family, loved ones and teammates as they honor his life and mourn his passing.”

Morris was selected by the Dolphins in the third round of the 1969 NFL Draft and played seven of his eight NFL seasons in Miami, where he averaged 4,133 rushing yards and 31 touchdowns.

Morris ranks fourth on Miami’s all-time rushing list with 3,877 yards, behind Csonka (6,737), Ricky Williams (6,436) and Ronnie Brown (4,815).

Morris was inducted into the Dolphins Walk of Fame in 2013.
