Buffalo Bills defensive back Aaron Williams was limited in Tuesday's practice but said he will be ready to play Thursday night against the Cleveland Browns. Williams did not finish Sunday's win over the Baltimore Ravens with a lower back injury and worked with the strength and conditioning staff during the early portion of Tuesday's practice. "I'll be ready to go" he said. Williams who returned to cornerback in the wake of Leodis McKelvin's injury did not take part in the defensive backs' walk-through early in Tuesday's practice. In his place the Bills had Justin Rogers Nickell Robey and Brandon Burton lined up at cornerback.
