The official web site of the Denver Broncos posted a team-produced video of a practice at Dove Valley during which center Dan Koppen was captured urinating on a tree next to the field.
The Broncos have removed the video from their web site. Thankfully, the folks at Denver Westword managed to get screen grabs before it came down. Number 67 can clearly be seen going number one in photos at Westword's site.
We will strike this one up to practice being far too intense for a potty break.
