NEW YORK, March 31 (Ticker) -- Stars Allen Iverson and Chris Webber came up with a huge performance just when the Philadelphia 76ers needed it.

Iverson scored 47 points and Webber added a season-high 34 as the 76ers ended a three-game slide with a 117-112 triumph over the New York Knicks, who have lost seven straight.

With just two wins in its previous 12 contests, Philadelphia (33-38) maintained its 1 1/2-game advantage over Chicago (32-40) for the eighth and final playoff spot in the Eastern Conference and within two games of idle Indiana (35-36) for seventh.

"Honestly, we know we're fighting for playoff position," Iverson said. "I just don't want to settle for the eighth spot. I feel like if we play these games out and win most of them then we can get up to the seventh or maybe even the sixth spot. But I think getting the seventh spot is reachable and that's what we're trying to do."

Playing a season-high 43 minutes because of injuries to Stephon Marbury and Steve Francis, rookie Nate Robinson scored a season-best 34 points, including seven during a 16-4 second-quarter charge that gave the Knicks their biggest lead at 58-46 with 2:03 left in the half.

"I was proud of our team tonight," New York coach Larry Brown said. "We didn't have Stephon (Marbury), Steve Francis, Quentin Richardson or Channing Frye and that's pretty tough. We competed at a high level with a very limited group."

"I am going to go at him (Iverson)," Robinson said. "I am going to make him play defense. That is what I tried to do tonight."

Philadelphia trimmed its deficit to 60-53 at the break, but during his halftime speech, coach Maurice Cheeks implored that his team picked it up defensively after letting the Knicks shoot 59 percent (23-of-39) from the floor.

"I said, 'Let's will it, let's get this one,'" Cheeks said. "We had to go get it and that's exactly what we did. I thought the second half was the reason why we won the game because it was just a will that helped us win a game."

The Sixers rallied in the final 10 minutes of the third quarter, outscoring the Knicks, 27-14, during the stretch. Iverson, who scored 30 points after halftime, netted 11 during the burst.

"It didn't seem like we wanted it," Iverson said. "It seemed like they were playing to try to get into the playoffs and we were a team just out there playing. We came back in the second half, had a sense of urgency and got back into the game."

Iverson's 3-pointer with 2:23 left in the period gave Philadelphia a 77-75 lead, an advantage it never relinquished.

After missing his first four shots, Iverson finished 13-of-29 from the floor and 18-of-20 from the free-throw line as the NBA's second-leading scorer reached the 30-point plateau for the first time since March 9.

Webber chipped in 13 points in the final period for the Sixers, who shot 56 percent (40-of-72), including 10-of-17 in the fourth quarter.

"I think Allen and Chris did a good job of just putting the ball in the hole," Philadelphia forward Andre Iguodala said. "Allen did a good job of putting the ball in the hole and Chris was tremendous at getting open looks."

"Down in the stretch of the game when we needed points, that's what they did," Cheeks said. "That's what they have to do."

Webber, who scored 18 points in the first half, made 14-of-23 shots and pulled down 12 rebounds for his third double-double in five games.

"It makes it that much more easier for me, especially when he gets that attention on the post and people double him," Iverson said of Webber. "When guys are doubling, trying to get the ball out of my hand, all I do is make one little pass at the free throw line and he's knocking them down, it's tough to stop.
