Watson (elbow) remained sidelined at practice Friday, Matt McMullen of the Chiefs' official site reports.
Watson hasn't practiced this week and seems likely to be ruled out ahead of Sunday's game against the Chargers. In Watson's looming absence, Mecole Hardman -- who was recently reacquired by the Chiefs -- is a candidate to be active this weekend in order to bolster the team's Week 7 WR depth.
