Boston — Marvin Williams didn't get the good news until he stepped off the plane from Atlanta.

There are no fines or suspensions for anyone on the Hawks or the Boston Celtics stemming from a second-quarter fracas Monday that was started by a shoving match between Kevin Garnett and Zaza Pachulia that resulted in four players receiving technical fouls.

Both teams will be a full strength for Game 5 tonight at TD Banknorth Garden.

"That's a relief," Williams said. "I would have been sick if they told me I couldn't play. But really, what was I going to do running down there, get knocked out? I didn't want any part of that."

Williams and Celtics center Kendrick Perkins both stepped on the court — Williams barely had a foot over the line — as Pachulia and Garnett had to be separated by players and coaches from both teams.

By league rule, players who leave the bench during an on-court skirmish receive an automatic one-game suspension.

Garnett shoved referee Eddie Rush, putting him in danger of being fined or suspended.

Hawks coach Mike Woodson acknowledged that he was worried after practice Tuesday, but he was relieved to learn that no one would be fined or suspended.

"Looking at what Marvin did, and the reaction of their guys," Woodson said, "They probably didn't realize where they were at. A lot of times guys get up off the bench and react to great plays on the floor or whatever and don't even realize where they are standing. Marvin obviously didn't know he was on the floor."

Home court advantage evident

While folks here are ready to panic after back-to-back losses by their beloved Celtics, their coach insists that the series hasn't even started yet.

"Nobody has won a road game," Doc Rivers said of the 2-2 split for the home teams.

That's the one, and perhaps only thing, both teams agree on right now.

"That's always been the test," Hawks captain and All-Star Joe Johnson said. "Somebody has to win on the road in order to draw blood. And it hasn't happened yet. That's the only way we can get out of this series is to take one on the road."

Celtics impressed by Johnson

Hawks fans weren't the only folks giddy after Johnson's fourth-quarter explosion in Game 4. Even the Celtics offered their compliments for a great playoff performance, one that cost them a chance at a commanding lead in this series.

"What you have to understand is this team is playing well," Garnett said. "We're playing good defense, and Joe Johnson had it going [Monday]. They moved the ball. They made shots. I'm not going to discount anything their doing.

"Joe Johnson is the most underrated player in our league besides [Detroit's] Rasheed Wallace. He's underrated. ... I'll give it to him. He played."
