The Broncos will be without receiver Wes Welker for their regular season finale against the Raiders.

Welker sustained a concussion in Week 14 and has been held out since. It was his second concussion in a span of a month.

Welker has had a history of concussions, which is part of the reason the Broncos are taking a cautious approach. Another concussion could leave Welker out for the postseason.

With Welker out, the Broncos figure to continue using Eric Decker in the slot with Andre Caldwell filling in at the outside receiver position.
