Chicago Bulls fans noticed a rather significant absence at the team's games this week: its six championship banners. As it turns out, there was a reason for that, and it doesn't make the story any more normal.
Per the Chicago Tribune, the banners were removed after sustaining "minor damage" during a concert featuring hard rock acts Disturbed, Three Days Grace and Sevendust, which reportedly used pyrotechnics directly underneath the banners.
The banners are now reportedly out for the season. It might be worth mentioning that Disturbed, the concert's headliner, is a local act out of Chicago.
