I have to say, this absolutely shocked me:

The flags at the north end of Lambeau Field flew at half staff Sunday morning in honor of a fallen Green Bay Packers hero.

It was a tribute ordered by Packers president Bob Harlan after he learned that Reggie White, one of the most revered players to put on a Packers uniform and a giant figure in the team's return to Super Bowl glory, had died at his home in Cornelius, N.C., at age 43.

The cause of death is still kind of vague... I've heard respiratory failure, and the article mentions the fact that Reggie suffered from sleep apnea. He was an incredible man, and has died far too young. Not only was he an absolutely great defensive player (arguably one of the best ever), but he worked hard in the community off the field as well. My thoughts and prayers go out to his family in their time of suffering.
