Buffalo Bills running back Karlos Williams is in the league's concussion protocol. He was not diagnosed during the game but was on Monday. He is now considered questionable for Week 5. With LeSean McCoy expected to miss a few more weeks, if Williams is out, Boobie Dixon will be the lead back in Buffalo. This is a situation to monitor throughout the week.
Fantasy Analysis:
If healthy, Williams is a high-end RB2 against the Tennessee Titans. The Bills are going to rely heavily on him. One thing that's getting lost among Fantasy owners is that Tyrod Taylor has been very good in real life.
