Courson, 50, a Super Bowl winner with Pittsburgh in 1978 and 1979, was killed at his home in Pennsylvania.

He played for the Steelers as an offensive lineman from 1978-1983 and then had two seasons with Tampa Bay.

An admitted steroid user, he testified before the US Federal Government reform committee earlier this year on the dangers of steroid use.

After retiring in 1985, Courson said steroids had caused him serious health problems, including a heart condition.

Since his retirement, Courson had lectured in schools about the dangers of steroid abuse.

In a statement, the Steelers said: "We will remember Steve for his many on-field contributions to our football club as well as for the caring person he was away from the game.

"Steve Courson will remain in our prayers and will be missed by everyone who knew him."
