Testaverde, named the starter ahead of Carr last week, was ruled out of the game 90 minutes before kickoff with a stiff back he developed Saturday.

Carr’s lone win as Panthers starter came against the Saints. The loudest cheer from the small crowd came when Moore, an undrafted rookie, entered the game. He was 8-for-14 for 66 yards and an interception.

It left Saints coach Sean Payton, who worked with Fox on former Giants coach Jim Fassel’s staff, feeling for Fox’s plight after Carolina lost starter Jake Delhomme to a season-ending elbow injury in Week 3.

“When you have to play your backup quarterback, and in this case play a guy who didn’t take a lot of reps during the week, the instability of that position is difficult,” Payton said.

The fans turned on Carr and the Panthers quickly. After Carr’s third-down pass was batted down near the end zone, John Kasay kicked a 29-yard field goal to cut the halftime deficit to 10-6.

But not before fans started chanted “We want Moore.”

“It’s not like we were purposely trying to not score points,” Carr said. “They were chanting ’More’ — that they wanted more points. And we were trying to give it to them.”

Notes: Reggie Bush, hampered by a bruised left shin, was held to nine carries for 32 yards. He caught three passes for 30 yards. ... The Panthers’ last home win was Nov. 19 of last season, 15-0 over St. Louis. ... Panthers CB Chris Gamble (broken thumb) missed the game and was replaced by Richard Marshall.
