Subs' playing time worth watching

BOSTON -- The Boston Celtics' locker room was mighty quiet 90 minutes before tipoff of Wednesday night's home opener against the Charlotte Bobcats at the TD Garden. Forward Shelden Williams held court with the media for a bit, saying he finally feels he has a chance to prove himself with this opportunity in Boston. A night after playing in his first nationally televised game in the NBA, Williams expressed excitement about opening night at the Garden, noting how raucous Cameron Indoor Stadium got on a nightly basis when he was at Duke.

Celtics coach Doc Rivers did most of the talking. Here are a few highlights:

Intense start: Rivers said he was happy with his minute distribution in Tuesday's win over the Cleveland Cavaliers in the season opener, but noted it was a "very intense game, an emotional game. You tend to spend more [energy] in those type of games. … It's opening night. We'll get another one like that tonight. The first three or four are always like that."

Keep an eye on how Rivers utilizes his bench (he only went four deep last night with Williams, Rasheed Wallace, Eddie House and Marquis Daniels). It should be interesting to see how the Big 3, with age such a prominent storyline in the preseason, respond to the first back-to-back of the season.

Injury report: Rivers said Brian Scalabrine (right ankle injury) will dress, but will not play. Asked if Scalabrine was "close," Rivers joked while standing outside the Celtics' locker room, "Yeah, he's right behind me." After some laughter, Rivers added, "I know he's going to dress; he's dressing because we have an extra uniform. I didn't ask [Celtics trainer] Eddie [Lacerte]. I know he's not playing in the first two [games]. I think he's close from the last talk I had."

Rivers had no update on Tony Allen, who remains sidelined indefinitely after hurting his ankle in his only preseason appearance.

Suspension suspense: Rivers did not offer an update on the indefinite suspension handed down to Glen Davis on Tuesday. Davis was involved in an off-court altercation that left him with a fractured right hand that required surgery. Rivers said he's removed from that process, focusing instead on coaching the team, but did note that Davis was not at the Garden on Wednesday.

Asked again about his take on the situation, Rivers reiterated his comments from Tuesday night. "He made a mistake and I'm mad at the mistake, but he's still part of our team," Rivers said. "You get upset at your kids, but they're still part of your family. That's the way I look at Baby. He's still part of this family and he's going to be an important part of this family."
