Bills DT Kyle Williams (back) is active for Sunday's Week 13 game against the Falcons. Williams was questionable coming in, so his presence will be a boost to the Bills' streaming D/ST. Stevie Johnson (groin) and Robert Woods (ankle) are also active and near 100 percent. The Bills' inactives: QB Jeff Tuel, RB Ronnie Wingo, CB Brandon Smith, LB Ty Powell, G J.J. Unga, G Antoine McClain and TE Chris Gragg.
