Hardman was listed as a limited participant at Wednesday's practice due to a pelvis injury.
The Chiefs activated Hardman from injured reserve earlier Wednesday after he hadn't played since Week 9 due to abdominal soreness, but given that he's still not practicing fully due to what's a related pelvis injury, the wideout's status for Saturday's game against the Raiders remains uncertain. Thursday's injury report will reveal whether Hardman approaches the contest with an injury designation or if he's cleared to play.
