AUBURN HILLS, Mich., June 4 (Ticker) -- Dwyane Wade could only sit and watch. And when he winced, you could not tell whether he was pained by his strained rib muscle or his team's play.

Playing without Wade, the Miami Heat was run off the court by the Detroit Pistons, who forced Game 7 of the Eastern Conference finals with a 91-66 victory.

An emerging superstar, Wade had averaged 30 points through the first four games before suffering the injury in the third quarter of Miami's Game 5 win. He tried to work through it but could not and left for good in the fourth quarter.

Wade did not practice Friday but intended to play, going through pregame workouts with Heat assistant Erik Spoelstra while wearing a gel-filled protective wrap. But he apparently felt too much pain and changed back into street clothes, watching helplessly from the bench as Miami's offense grinded to a halt without him.

"Obviously, not having him, that impacted the game so much," Pistons coach Larry Brown said. "You know, Dwyane ... makes everybody better. Dwyane has the same effect on the game at both ends. Obviously it helped."

Matched up with a desperate, defensive-minded Detroit, Miami was held under 80 points for just the third time this season - all against the Pistons. The Heat's total was a franchise low for a playoff game, which includes all those 1990s scrums against the New York Knicks.

Without Wade, the Heat had no one to start their offense and no one to bail them out. In the first half, Miami had 14 baskets and 12 turnovers, digging itself a 44-32 hole. It was even worse in the third quarter, which Detroit closed with a 9-0 burst for a 69-45 bulge.

"They're a different ballclub. There's less penetration," Pistons forward Rasheed Wallace said. "Wade likes to get to the basket, so there was less penetration."

"We defended the way we want to defend," Pistons guard Richard Hamilton said. "In the first half, they only had 32 points, so we tried to force them to get turnovers and things like that."

The top-seeded Heat tried to force-feed superstar center Shaquille O'Neal, who has been nursing a bruised thigh throughout the postseason. O'Neal had his best statistical game of the series with 24 points and 13 rebounds but also committed six turnovers - as many as the Pistons.

"We tried to ... give him different looks as opposed to already being behind him on three-quarter, just tried to find a little bit of double(-team) early," Wallace said. "(We) just tried to throw him off, keep him off-balance."

"I think we had trouble taking care of the ball," O'Neal said. "We were right there in the first quarter, but the second quarter we just had too many turnovers. I think we had 19 turnovers and just didn't take care of the ball. They got a lot of easy baskets."

The injuries continued to pile up as well. Swingman Eddie Jones, already playing with a bruised foot, suffered a cut over his right eye in the third quarter that required stitches to close.

Hamilton scored 24 points on 10-of-17 shooting for the second-seeded Pistons, who scored 25 points off 19 forced turnovers and 19 fast-break points. Tayshaun Prince had 16 points and nine rebounds and Chauncey Billups scored 14 points.

"It's just amazing when you're down, the more desperate, the more aggressive you get," Prince said.

"Our half-court defense was not all that bad, but we couldn't rebound and we could not take care of the ball," Heat coach Stan Van Gundy said. "They dominated us. After the first quarter, they totally dominated us and I really don't have a lot else to tell you."

On Monday, Detroit will try for a rare Game 7 road win, which has happened just 16 times in NBA history. Wade is expected to try to play.

"It's win or go home," Heat guard Damon Jones said. "And I don't fish."

"I'm nervous about it," Brown said. "But I hope my players enjoy this. The thing that I dread about Game 7 is for players to worry about making mistakes. I just want them to enjoy it and do the best they can and hopefully the best team will win."

Rasual Butler started for Wade and scored 13 points, including a jumper that gave the Heat their last lead at 20-19 with 9:56 left in the second quarter. They went nearly five minutes without a point as the Pistons rattled off 13 points, highlighted by a pair of 3-pointers by Prince.

"They speeded us up a little bit," Jones said. "We turned the basketball over too many times and they got to the open court and got some fast-break points, and it was a free-for-all from there."

Butler's jumper and 3-pointer capped a 12-2 surge that made it a game again as Miami closed to 34-32 with 1:54 to go. But the Heat unraveled again as Hamilton scored five points in a 10-0 burst that closed the half.

Detroit began the third quarter with a 9-2 run and ended it with nine straight points, prompting garbage time.
