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.
A fifth-round pick out of Florida State, Williams has rushed 24 times for 186 yards (7.8 YPC) and three touchdowns in the first three games of his career. The power back has impressed going back to training camp.
With only Anthony Dixon and fullback Jerome Felton in reserve, look for the Bills to sign another tailback in the next couple of days.
