Chargers' Keenan Allen: Won't play Sunday

Allen (heel) has been ruled out for Sunday's game against the Broncos.

The same applies to Joshua Palmer (concussion), which sets the stage for Quentin Johnston, Alex Erickson, Jalen Guyton and Derius Davis to lead the Chargers' Week 17 WR corps. Allen now will target a potential return to action in the team's season finale against the Chiefs.
