Hall of Fame defensive end Chris Doleman, who became one of the NFL’s most feared pass rushers during 15 seasons in the league, has died.

He was 58. There was no word on the timing of Doleman’s death, but he had surgery in January 2018 to remove a brain tumor. He was said to have had a long battle with cancer.

Doleman spent most of his career with the Minnesota Vikings. He also had stints with Atlanta and San Francisco.
