PHILADELPHIA -- The buzz at the start was for Allen Iverson's ceremonial return.

By the end, more than 20,000 fans were on their feet and going wild for Jrue Holiday, Elton Brand, Andre Iguodala and the rugged-and-determined play that kept the eighth-seeded Philadelphia 76ers alive for at least one more game.

Yes, the Sixers are talking about Game 7 -- and they're taking this improbable postseason run back to Boston.

Holiday scored 20 points, and Brand had 13 points and 10 rebounds to lead the Sixers to an 82-75 victory over the Celtics on Wednesday night that tied the Eastern Conference semifinals.

No team has won consecutive games in a series in which neither team has played well enough to seize control. But the Sixers were good enough to win Game 6, improving to 5-0 this postseason in games after a loss.

"Game 7," coach Doug Collins said. "That's all we wanted was to win tonight and give ourselves a chance to go into Boston and see what happens on Saturday."

Paul Pierce, Kevin Garnett, Ray Allen and Rajon Rondo could be playing their last game together Saturday night if they can't find a way to hang onto the ball and put away a Sixers team that won't quit.

Boston has learned three times already how difficult that can be.

The fun started when the not-quite retired Iverson earned a roaring standing ovation when he presented the game ball.

It ended with the song, "I'm Shipping Up to Boston," blasting through the arena.

"I want more," Collins said. "We're going to get greedy. We want more."

The Celtics posted ugly numbers across the board: Blame the loss on the 33 percent shooting, the 17 turnovers or the 3 for 14 3-point shooting. Either way, there's enough to go around. Pierce had 24 points and 10 rebounds, and Garnett had 20 points and 11 boards.

"We found a way to stay in the game, for the most part," Pierce said.

They did because the Sixers again failed to put up the sparkling numbers in the box score usually required for a deep postseason run. They missed 8 of 9 3-pointers, shot a woeful 17 of 28 from the free-throw line and had 12 turnovers.

But when the Sixers really needed that game-changing basket, there was Evan Turner twisting and fighting through defenders down the lane. When the Sixers needed a stop, there was Brand, ripping a rebound away from Boston, even with painful neck and shoulder injuries that keep him awake at night.

"When you get out there, you don't feel much," Brand said. "You've got the adrenaline flowing. You're banging and fighting. That's why coach has confidence in me to play 34 minutes."

The Sixers wrote "Huddle Up and Fight" on their locker room chalkboard.

They did just that and are now one win away from reaching the conference finals for the first time since 2001.

Iverson was the MVP of that run.

Maybe a little of that ol' A.I. magic rubbed off in Game 6.

Unlike Game 5, when the Sixers collapsed in the third quarter and blew a lead, they suddenly found a groove in front of 20,403 fans.

The Sixers started hitting free throws, kept turnovers to a minimum (two), and fed the ball to a starting lineup that had been largely outproduced by a fantastic bench.

Turner was fouled on a go-ahead layup but missed from the line. That made the Sixers 5 of 13 while the Celtics were 14 of 14.
