Williams (heel) doesn't have an injury designation for Thursday's game against the Chiefs, Daniel Popper of The Athletic reports.
Meanwhile, fellow wideout Keenan Allen is back from the reserve/COVID-19 list after missing Sunday's 37-21 win over the Giants, and running back Austin Ekeler -- who is questionable with an ankle injury -- also has a shot to play Thursday after limited practices Tuesday and Wednesday. Things have gone better for Williams in recent weeks following a midseason slump, but he's still ranked as a distant No. 2 option in the passing game behind Allen, seeing between five and eight targets in each of the past eight games.
