Peyton Manning

The biggest question in the Broncos' near future remains Peyton Manning's health and potential return from a partially torn left plantar fascia.

The veteran quarterback visited last week in North Carolina with Dr. Robert Anderson, who recommended Manning wear a cast on his left foot for a week.

Monday, after the Broncos' recorded their second victory in Manning's absence, coach Gary Kubiak said questions remain about Manning's timetable.

"The biggest question this week is really going to be about when the cast comes off — does it come off early this week or does it come off at the end of the week?" Kubiak said. "The progress has been good. The next step, when he comes out of it, is to get back into the rehab process into the field. We'll just take it a day at a time right now."

If Manning's cast doesn't come off until later in the week, however, a return for the Broncos' Dec. 13 game against Oakland might be in jeopardy, the story said. Of course, the bigger question is do the Broncos stick with backup Brock Osweiler, who led the team to a win over New England in Week 12.
