Perkins out of decider

Perkins, the team's defensive enforcer and key rebounder, has multiple ligament sprains in his right knee suffered during Tuesday's Game Six.

"Well, he's not going to go. I'll tell you that now. We'll figure out the match-ups later," Celtics coach Doc Rivers said.

The Celtics will likely start either Glen Davis or veteran Rasheed Wallace in place of Perkins as they attempt to rebound from Tuesday's 67-point performance that was the second-lowest offensive output ever in an NBA Finals.

"Everyone knows what they have to do - for us to accomplish what we want we have to do it on their floor," said Boston's Ray Allen. "We play well with our backs against the wall."

In their quest to win a second straight title, the Lakers will take comfort in playing at Staples Center, where they have a 10-1 record this post-season.

In Game Six in Los Angeles, the Lakers' bench was revitalized behind strong reserve performances from Lamar Odom, Jordan Farmar, Sasha Vujacic and Shannon Brown.

"Historically, your bench is much more comfortable on their home floor," said Los Angeles coach Phil Jackson, who is facing his first Game Seven in an NBA Finals. "I was happy with their purpose and direction."

Leading the way for Los Angeles in the pressure-packed deciding contest will be Spanish forward Pau Gasol along with four-times champions Kobe Bryant and Derek Fisher.

Bryant will be looking to further his resume by joining Hall of Fame Lakers guard Magic Johnson as a five-time title winner, but the 12-times All-Star said he is only focused on the game at hand.

"It's a game we have to win; simple as that," Bryant said. "The opportunity is not something that makes me happy - what makes me happy is winning."
