Peyton Manning in walking boot, still sidelined
Added coach Gary Kubiak: "We're totally committed to getting our quarterback, getting Peyton healthy, and getting him back and nothing's changed. And nothing's changed where we're heading this week, Brock's our starter this week and we're all in getting ready for San Diego. We're week to week and we're doing everything we can to win the next football game, but absolutely nothing has changed."
