Jim Clack, a guard on two Super Bowl-winning Steelers teams in the 1970s, died of heart failure. He was 58.

Clack had fought neck and throat cancer for about four years before his death at Moses Cone Memorial Hospital in Greensboro, his wife, Susan Clack, said.

"We are deeply saddened to learn of the death of Jim Clack after suffering from a lengthy illness," said Steelers president Art Rooney, II.  "Jim was a vital member of our first two Super Bowl Championship teams. Our prayers go out to his wife, Susan, and the entire Clack family."

Clack, who helped the Steelers win Super Bowls following the 1974 and 1975 seasons, played in 146 NFL games between 1971 and 1981. He played for Pittsburgh for seven seasons before joining the New York Giants in 1978 and playing for four more years.

Born in Rocky Mount, N.C., Clack attended Wake Forest and entered the school's hall of fame in 1991. He was inducted into the North Carolina Sports Hall of Fame in 2004.

He returned to North Carolina after his football career, developing commercial and residential real estate and owning a restaurant. He started a sales training business and worked as a motivational speaker.

Clack also is survived by his stepchildren, Joseph and Lindsay Curtis, both of Wilmington.

A funeral will be held at Cornerstone Baptist Church with burial at Westminster Gardens in Greensboro. A memorial service in scheduled for Tuesday at Lakeside Baptist Church in Rocky Mount.
