Allen (shoulder) was a limited participant at practice Wednesday, Eric Smith of the Chargers' official site reports.
Allen was listed as questionable ahead of this past Sunday's loss to the Packers with an AC joint sprain in his shoulder, but the wideout played through the issue and finished with 10 receptions for 116 yards and a touchdown on 16 targets. With no reported setbacks coming out of that contest, Allen's limitations Wednesday may well have been maintenance-related.
