Searcy injured his hamstring early in last week's loss to Denver, and was unable to return to the game. He put on a jersey for all three days of practice this week, but was extremely limited in what he could do. With Searcy out of the lineup, second-year pro Duke Williams will start against Aaron Rodgers and the Packers' vaunted passing attack, with recent free agent acquisition Bacarri Rambo very likely to be active as the top reserve.
His role now bigger than ever as a nominal starter, Searcy is in the midst of an excellent season with 47 tackles, a career-high three interceptions, and a fumble recovery.
Reserve tight end Chris Gragg, who has missed two straight games with a knee injury, has also been ruled out after not practicing at all this week.
Things are looking far more optimistic for the rest of the players on the Bills' injury report - a list that includes key names like defensive end Jarius Wynn, defensive tackle Stefan Charles, and kicker Dan Carpenter. Wynn's return will be of particularly vital performance as the Bills try to harass the league's best quarterback on Sunday.
