Jesse Powell, a linebacker for the unbeaten 1972 Dolphins, has died at a hospital in West Texas.
A spokesman for University Medical Center in Lubbock says Powell died Thursday. He was 65. No cause of death was provided Friday by UMC.
Powell was born in the Texas Panhandle town of Matador. He starred at West Texas State University, now West Texas A&M, before the Dolphins chose him in the ninth round of the 1969 draft.
Powell spent his five-year NFL career with Miami, including a perfect 17-0 season leading to a Super Bowl victory over Washington.
Powell, who quit the NFL following knee surgery, was an insurance agent in Lubbock until his recent retirement.
A memorial service has been scheduled for Tuesday at Monterey Church of Christ in Lubbock.
