Howard Twilley, a receiver on the Miami Dolphins' undefeated 1972 team and two-time Super Bowl champion, died on Wednesday at the age of 81. The team announced the news on Friday.

Twilley was a member of the first Dolphins team in 1966 and one of two players from that roster to be on the 1972 Super Bowl championship team. He caught the first touchdown of the game in Super Bowl VII, a 14-7 victory over Washington.

Those 1972 Dolphins went 14-0 in the regular season, then 3-0 in the playoffs, and they stand as the lone NFL team to go through the regular season and playoffs without a loss. Miami won a second consecutive Super Bowl title during the following season, going 12-2 and defeating the Minnesota Vikings 24-7 to win the title.

Twilley was the third-leading receiver on the 1972 Dolphins, catching 20 passes for 364 yards and three touchdowns. That was the third-best season he had as a pro. For his career, Twilley compiled 212 receptions for 3,064 yards and 23 TDs in 11 seasons.

Twilley played his college football at Tulsa, where he caught 261 passes for 3,343 yards and 32 TDs in three seasons from 1963-65. In his junior and senior seasons, he led the nation in catches, receiving yardage and receiving touchdowns. His No. 81 was retired by the football program.

A two-time All-American, he was the runner-up for the Heisman Trophy behind USC's Mike Garrett in 1965. That season, Twilley had 134 receptions for 1,779 yards and 16 scores for the 8-3 Golden Hurricane.

Twilley was inducted into the College Football Hall of Fame in 1992. He is also in the Tulsa Athletic Hall of Fame in addition to the Oklahoma Hall of Fame.
