From the Associated Press :
Steve Courson, the former offensive lineman for the Pittsburgh Steelers who developed a heart problem after becoming one of the first NFL players to acknowledge using steroids, was killed Thursday when a tree he was cutting fell on him.
Courson, 50, was using a chain saw to cut down a dead 44-foot tall tree with a circumference of 5 feet when it fell on him, according to state police. The accident happened around 1 p.m. ET at his home in Henry Clay Township, Fayette County.
Roger Victor, an investigator for the Fayette County coroner, said Courson was apparently trying get his dog out of the tree’s way. “The wind was blowing, the tree snapped and it fell on him and his dog,” Victor said. The dog was injured and taken to a vet.
