"Three Broncos offensive starters were missing from the start of practice today as the team began preparing for Sunday's game against Chicago.

Left tackle Ryan Clady?, running back Willis McGahee? and wide receiver Eddie Royal? are all being held out of practice because of injuries suffered last week in Minnesota.

Clady appeared to suffer a knee injury on the team's final offensive play in the 35-32 win against the Vikings. McGahee limped off the field late in that game as well.

Royal suffered a concussion in a collision with teammate Matt Willis on a punt return."
