The Buffalo Bills are prepared to turn their backfield over to rookie Karlos Williams versus the New York Giants in Week 4.
Nursing a nagging hamstring injury, LeSean McCoy is unlikely to play this week, NFL Media's Rand Getlin reported, via a source briefed on the injury.
Although a quick-footed McCoy appeared to be over the hump in Week 2, he spent much of Sunday's victory on the stationary bike, trying to keep his hamstring loose.
The coaching staff's confidence in Williams is likely the primary reason behind this week's cautious approach to McCoy's recovery.
