Keenan Allen, wide receiver for the Los Angeles Chargers, has been ruled out for Saturday night's game against the Bills due to a heel injury. This will be his second consecutive game missed. Joshua Palmer and Quentin Johnston are expected to lead the Chargers' wide receiver corps in Week 16, with Jalen Guyton and Alex Erickson also in the mix. Allen's next opportunity to return to action will be on December 31 against the Broncos.
