Keenan Allen, wide receiver for the Los Angeles Chargers, did not participate in Monday's practice estimate due to a heel injury. Allen set a new personal best and franchise record with 108 receptions on the season in the previous game against the Broncos. His status for Thursday's road game in Vegas is uncertain and bears monitoring. Quarterback Justin Herbert is also expected to miss Thursday's game, so if Allen is able to play, he'll likely be catching passes from backup Easton Stick.
