Williams (heel) caught just three of his nine targets for 49 yards in the 34-28 loss to the Chiefs on Thursday.
Williams briefly left the game in the first quarter after appearing to injure his shoulder on a dropped touchdown pass, but the big-bodied target returned shortly after and looked no worse for the wear. After a scintillating start to the season, the 2017 first-round pick has cratered back down to earth with just one touchdown over the last eight games. That could change with a relatively easy matchup against the Texans on tap for Week 16, a game in which the Chargers need to win in order to stay in the hunt for a possible wild-card berth.
