Broncos rookie quarterback Tim Tebow showed up to practice on Tuesday with a shaved head. Denver linebacker Wesley Woodyard gave Tebow his now-infamous haircut a few days ago, shaving the top and leaving a ring of hair that made him look like a monk. "I was like, 'I've got the perfect idea for you," ' Woodyard recounted. "So, I told him just to sit in the chair and we were going to take it from there."
