At one point in the second half Sunday, the Raiders secondary consisted of cornerbacks Stanford Routt, Joe Porter and Chimdi Chekwa, and safeties Jerome Boyd and Matt Giordano.
Starting strong safety Michael Huff (concussion) and cornerback Chris Johnson (hamstring) left in the first half and did not return. Rookie DeMarcus Van Dyke, with a laceration on his knee, was inactive. Strong safety Tyvon Branch left briefly with an undisclosed injury but later returned.
Somehow, the Raiders held up without the need for baling wire, duct tape and chewing gum.
New York Jets quarterback Mark Sanchez had 369 yards passing, but Branch had a big interception to halt one drive, and the Raiders did enough with some zone coverages to throw off Sanchez while scoring 24 straight points from the late second to early fourth quarters.
Porter is an undrafted free agent who was on the practice squad last year. Chekwa is a fourth-round pick who struggled a week earlier in a loss in Buffalo. Boyd has been predominantly a practice squad player until this season, and Giordano was cut by the Raiders at the final cutdown only to be brought back two days later.
Yet the Raiders did enough with the makeshift secondary to win the game.
"The coaches do a great job getting us prepared,'' Porter said. "We'll get quizzed not only on our position, but positions we could possibly play. Everything fits like a puzzle. To be able to apply it like that on the field was huge.'
Sanchez conceded the Raiders' mix of zone defenses achieved its goal.
"Traditionally they're a man-to-man, in-your-face, press, jam you at the line kind of group, and they completely changed their stripes," Sanchez said. "They played a lot of zone. They matched a lot of zone underneath and kind of throttled us a little bit in the third quarter."
Branch, who missed a potential interception against Buffalo only to see it turn into a Bills touchdown, read a Sanchez scramble perfectly for an end-zone interception with New York at the Raiders' 24.
"We were playing scramble rules, they were running their routes, I stayed deep and got lucky," Branch said.
"Our front seven is one of the best in football, and any time we're allowed to rush the passer and they're just going to keep their line in to block, we can rush against anybody,'' Seymour said.
Regarding the crossed-arms gesture after his sack with Kelly, Seymour said, "When I throw up the 'X,' that means it's time to put the kids to bed. It's X-rated out there."
"Last week I threw for 300 yards (323) and we lost," Campbell said. "This week I throw for 150 and we win. It's not about that for me, it's about moving the team, keeping them in good position to score and having a chance at the end to win it."
Campbell did not turn the ball over -- his only turnover through three games is a Hail Mary interception at the end of the Buffalo game -- and has been sacked just twice in three games in part because he has unloaded the ball when in trouble.
"I wouldn't say we kept things safe,'' Campbell said. "But we had to monitor the game.''
Other players who were injured besides Reece, Johnson and Huff were McFadden (groin), defensive end Matt Shaughnessy (shoulder) and linebacker Quentin Groves (quad), although none of the latter three missed significant game time.
