Bengals (0-6) at Bills (6-1) TV: 9 p.m., channels 13, 7
Line: Bills by 13 1/2 .
Key injuries: Bengals: RB Eric Ball (ankle) out.
Outlook: Billed by some as the battle between no-huddle offenses, the game is more likely to turn on defense, where neither team has been particularly effective. The Bengals have the NFL's worst-ranked defense. They've allowed 171 points, 5 fewer than the Colts, who have played 1 more game. The Bills' defense, forced into more playing time because of Buffalo's league-low average possession time of 24:05, has given up a league-high 2,334 yards.
