CBS football commentator Hank Stram, former coach of the Kansas Chiefs and the New Orleans Saints, was scheduled to undergo open-heart surgery today in Indianapolis.

Stram, 65, told Len Dawson, a former Chiefs quarterback who is now a broadcaster in Kansas City, about the surgery Monday.

Stram, who was hospitalized Saturday after complaining of dizziness, was listed in serious but stable condition night at Methodist Hospital in Indianapolis.

Stram was in Indianapolis to work Sunday’s Colt-Chicago Bear game.

Several of Stram’s co-workers said calcium deposits apparently were affecting Stram’s circulatory system. Jack Buck, one of Stram’s colleagues at CBS, said the condition apparently was something Stram has had all of his life.
