Steven Jackson scored on a pair of short runs for the Rams and Kevin Curtis got the go-ahead touchdown on a 5-yard reverse with 5:58 to go in a come-from-behind 28-17 victory.
Behind 36-year-old backup quarterback Jamie Martin -- who was making only his fourth career start -- St. Louis stopped a three-game losing streak and kept hope alive that they'll still be a factor if they ever get healthy. Mike Martz is in the hospital with an infection and the Rams' quarterback and two starting wide receivers were in street clothes because of injuries.
"Just somehow to be able to get a win, that's huge with all those guys out," Martin said. "We need to just keep it going and hopefully get another one next week, and when they get back we'll be rolling."
A pair of failed trick plays came back to haunt the Saints (2-5), who squandered a 14-point first-quarter lead and have lost three in a row. A quarterback sneak on a fake field goal on fourth-and-1 was stuffed for no gain near the end of the third quarter, and Donte' Stallworth 's fumble on a fourth-quarter reverse led to the go-ahead score. The Rams also blocked a field-goal attempt in the second quarter.
"We had chances to make plays and we just didn't step up and make enough plays," coach Jim Haslett said. "They made plays when they had to, that's basically what it boiled down to."
Martin, subbing for the injured Marc Bulger, was ineffective most of the day. But he hit Curtis for a 42-yard gain to the 6 to set up the winning score, and then led the blocking on Curtis' clinching TD run after the wide receiver took a handoff from Jackson.
"I did just enough," Martin said. "I'm not a lineman; I just tried to shield him and let Kevin do what he wanted to do."
Martin, who threw two crucial interceptions in a loss at Indianapolis in Week 6 after Bulger was hurt, was 18 for 29 for 198 yards with no interceptions against the Saints. The 36-year-old won for the first time in four career starts.
Bulger is out with a sprained shoulder and Torry Holt (knee) and Isaac Bruce (turf toe) also did not dress, robbing the Rams of considerable firepower.
Aaron Brooks threw touchdown passes on the Saints' first two drives. After that, the team without a home fizzled and its three-game winning streak in St. Louis came to an end.
Furrey's touchdown return came a play after a defensive holding call on third down gave the Saints a fresh set of downs at their own 42.
The Saints wanted to challenge the interception return but couldn't because they were out of timeouts, and although the play ended with 1:55 left, it began with 2:10 to go and the NFL only takes over after the two-minute warning. Tight end Ernie Conwell claimed he had been down before losing the ball.
"I would bet -- well, I'm not a betting man -- but I feel 99.9 percent confident that I had possession of the ball and that I was down by contact," Conwell said. "I went over to the official and told him I had possession, that you guys have got to review that."
Referee Mike Carey said the crew saw a "bobbling pass reception with no control. While the ball was still loose, it was taken away by the Rams for a touchdown."
Brooks was 18 for 39 for 230 yards and threw touchdown passes of 11 yards to Stallworth and 17 yards to Az-Zahir Hakim for a quick 14-0 lead with five minutes left in the first quarter.
Jackson had a 43-yard gain on the Rams' first play, but that was their only first down until midway through the second quarter. Jackson's 6-yard touchdown run came one play after a 42-yard pass interference call on Steve Gleason.
Notes: Rams DT Damione Lewis was ejected midway through the first quarter after punching Saints C LeCharles Bentley in the groin area. Bentley wants Lewis to be suspended, saying "Maybe that's how he was raised. He's a Miami guy so what do you expect?" ... Rams DE Leonard Little missed the game following the shooting death of his brother. ... Hakim caught six passes for 100 yards, his first 100-yard game of the season.
