Former BYU standout and Oakland Raider tight end Todd Christensen died Wednesday morning due to complications from surgery, BYU announced.

Christensen was 57 and, per the Salt Lake Tribune, had battled liver disease and other illnesses.

As a Raider, Christensen won two Super Bowls (1980, 1983), attended five Pro Bowls (1983-1987), and twice led the NFL in receptions. In 1983, Christensen caught 92 passes for a career-high 1,247 yards and 12 touchdowns, helping lead the Raiders to a 38-9 win over the Washington Redskins in Super Bowl XVIII.

Christensen retired from football in 1988.

Following his football career Christensen also gained fame as a broadcaster, working as an NFL analyst for NBC in the early 1990s, briefly co-hosting the fondly remembered 'American Gladiators' with Mike Adamle, and appearing as a color analyst for ESPN, the mtn., and CBS Sports Network.

A Pennsylvania native who grew up in Eugene, Oregon, Christensen earned a scholarship with the Cougars and played from 1974 to 1977, starring as an all-purpose running back. Christensen led the team in receiving three times and finishing with 152 career receptions for 1,568 yards and 15 touchdowns.

The Dallas Cowboys took Christensen in the second round of the 1978 draft, with Christensen moving to the Raiders -- and to tight end -- in 1979.

He was inducted into the BYU Sports Hall of Fame in 1992..
