Karlos Williams not at Bills' practice Thursday

Buffalo Bills running back Karlos Williams (concussion) is not practicing on Thursday.

What It Means:

Williams wasn't able to practice Wednesday, either, as he is still in the league's concussion protocol. If he can't go, head coach Rex Ryan has said that Boobie Dixon will get the start.

Whoever does get the start will be in a positive situation. The Bills' offense fourth in Adjusted Rushing Net Expected Points (NEP) per play. Part of that is due to Williams' efficiency, but some credit also must go to the offensive line. Additionally, their opponent -- the Tennessee Titans -- ranks 25th in Adjusted Defensive Rushing NEP per play. If Williams can't go, Dixon may warrant consideration in a tournament for daily leagues.
