Between dealing with a shoulder injury and LeSean McCoy's improvement, Karlos Williams' fantasy football value has cratered in the second half of the season. Williams received a bit of a boost Sunday, but it's still a bit early to start buying the 22-year-old running back as a strong fantasy candidate again.
The Buffalo Bills announced McCoy suffered a knee injury in the team's Week 15 matchup with the Washington Redskins.
While that opened up more playing time for Williams in the short term, it may not be the case beyond Sunday. According to Pro Football Talk, McCoy's injury isn't considered to be serious, at least before he undergoes further testing.
