First quarter: Safety dance
Chris Kelsay started at right defensive end for the first time since the season opener, and made his presence felt early. Kelsay bowled over Cardinals left tackle D’Anthony Batiste for a sack that produced a safety for Buffalo’s first points. It was the Bills’ first safety since Kelvin Sheppard tackled Daniel Thomas in the end zone at Miami on Nov. 20, 2011.
The sack gave Kelsay 31.5 for his career, tying Jeff Wright for ninth place on the Bills’ all-time list.
Kelsay earlier on the drive had dropped Cardinals running back LaRod Stephens-Howling for a loss of 1 yard, then later in the quarter stopped Cardinals running back William Powell after a gain of 1 yard.
Fumble! Fred Jackson’s fumble on the first play from scrimmage was the Bills’ sixth lost fumble on the season, one more than they had all of last year. Jackson had the ball knocked out by the Cardinals’ Daryl Washington. It was recovered by Arizona cornerback William Gay.
Stats watch: A game after going 2 for 10 on third down, the Bills were 3 of 4 in the quarter.

Second quarter: A bargain RB
Cardinals running back William Powell led the NFL in rushing in the preseason, with 249 yards on 42 attempts. Not bad for a player who a year ago was working at a Best Buy in Kansas.
The Cardinals signed Powell as an undrafted rookie free agent last season even though he had only 23 carries in two seasons at Kansas State. He was cut at the end of the preseason and, before being signed to the practice squad late in 2011, worked at the Best Buy.
Powell moved up on the Cards’ depth chart after injuries to Beanie Wells and Ryan Williams. He carried six times for 34 yards in the second quarter.
It’s a fake! The Cardinals converted a fourth-and-2 from their own 33-yard line with 1:40 left in the first half when Rashad Johnson took the snap on a fake punt and ran around right edge. Johnson picked up 24 yards down to the Bills’ 43-yard line, but the Cards’ drive stalled.
Challenge flag: Bills coach Chan Gailey made his first challenge of the season, challenging the spot on a completion to Cards receiver Andre Roberts that gave Arizona a first down. The ruling was upheld.

Third quarter: Motoring ahead

The Bills’ entire rushing arsenal was on display on their five-play, 80-yard touchdown drive. C.J. Spiller ripped off gains of 7 and 33 yards to set up the Bills at the Arizona 17, then the Bills turned to the Wildcat. Brad Smith faked a handoff to a motioning Spiller, then took off around right end for a 16-yard gain to the Cardinals’ 1.
Fred Jackson finished things from there, plunging into the end zone for his 17th career rushing touchdown.
Who’s that blocker? The Bills used defensive tackle Kyle Williams as a blocker on Jackson’s 1-yard touchdown plunge with 27 seconds to go in the quarter. Williams got a piece of Cardinals All-Pro defensive tackle Darnell Dockett, but didn’t really factor into the play.
Moving the chains: The Bills picked up six first downs in the quarter, helping them overcome an average drive start at their own 16-yard line.
Living dangerously: Shawn Powell boomed a 55-yard punt to the Arizona 6, but gave Cards returner Patrick Peterson too much room. Peterson took the return 20 yards, coming close to breaking it.

Fourth quarter/OT: Just for kicks
Jay Feely’s career long before Sunday? That would be 55 yards. Feely shattered that when he buried a 61-yard field goal with 1:14 left on the clock, tying the game at 16-16.
Feely had a chance to win it with three seconds left, but his attempt from 38 yards was partially blocked by Bills defensive tackle Alex Carrington, hit the left upright and fell to the ground, no good.
The Bills elected not to try a 53-yard field goal with Rian Lindell on their first possession of the overtime, and punted. The ball was nearly downed at the 1, but Ruvell Martin’s foot was on the goal line while he was touching the ball and it was ruled a touchback.
Bills coach Chan Gailey’s reason for punting: He wanted to pin the Cards deep with their backup quarterback in the game. Jairus Byrd intercepted John Skelton three plays later to set up Lindell’s game-winner.
Kolb goes down: Skelton was in the game because Arizona starter Kevin Kolb was hurt just before the two-minute warning, when he attempted to scramble and was hit by Bills defensive linemen Chris Kelsay and Carrington.
