The visitation was held at Taylor Funeral Home on the South Side.
Duerson died of a self-inflicted gunshot wound to the chest last week. He was a Notre Dame graduate who was an outstanding defensive back. He played in four pro bowls and was a key member of the Bears 1985 Super Bowl champs.
Duerson asked that his brain be donated to science for research into concussions, which are brain injuries often suffered by football players."It's a real difficult time. Our family is suffering. We're just trying to get through this. It's tough for us. It's shocking. It's a tragedy. It's a crisis. But you know, my dad, he's a good man. He's a great father. And I'm really proud of him," said Brock Duerson, son.
"Dave was always a person who was gonna lift someone up. So to have him do something like that, he was forward thinking even all the way to the end," said Markham Thomas, friend.
Duerson's funeral will be at 11 a.m. Saturday at Antioch Missionary Baptist Church on South Stewart.
