The Dallas Cowboys are mourning the loss of one of the franchise's celebrated defensive players. 

Lee Roy Jordan, a star linebacker who played on the Cowboys' first Super Bowl-winning team in 1971, has died at age 84.

Jordan played under the late Paul "Bear" Bryant during his standout career at Alabama. Dallas selected him in the first round of the 1963 NFL Draft.

Jordan was a big part of the team's "Doomsday Defense" that carried the Cowboys to a Super Bowl title in a 24-3 victory over the Miami Dolphins during the 1971 season. He retired from the NFL in 1976. The Cowboys won their second championship the following year.

A five-time Pro Bowler, Jordan was the first player inducted into the team's Ring of Honor under Jerry Jones' ownership.

Jordan remains second on the team's all-time tackles list with 1,236. Darren Woodson, a safety on the Dallas teams that won three Super Bowls in the 1990s, has 1,350.
