WALTHAM, Mass. -- A quick rundown on the news and notes from Saturday's practice at the Sports Authority Training Center at HealthPoint, where the Celtics got back to work after their 11-game winning streak was snapped Friday night at the TD Garden:

Celtics watch film, go hard in open practice

The Celtics watched film of their 98-97 loss to the Phialdelphia 76ers and coach Doc Rivers opined that the team, "had so much slippage, offensively and defensively, it's amazing we were actually in the game."

The coaching staff pointed out all of those errors in a lengthy film session, then ran the players through a fairly strenuous 65-minute session that included a hefty amount of 5-on-5 work.

"You'd rather not get in the habit of practicing after a loss," said Rivers. "I don't think our guys like having these type of practices and film sessions."

The Celtics held an open workout, but that didn't make it any easier for the players, and they embraced the intensity of the session -- showing improvement over Thursday's sloppy practice.

"Today was a lot better," said Celtics captain Paul Pierce. "Open practice or not, it was important for us to get better today, and we did that."

Pierce wants Wallace to 'Slow it down'

Celtics forward Rasheed Wallace, ejected from Friday's loss after receiving a double technical in the second quarter, did not address reporters following Saturday's session.

Pierce said he's not overly concerned with what transpired, but with Wallace now at 10 technical fouls through 25 games, Pierce does hope he slows it down a bit moving forward.

"You know Rasheed is going to be Rasheed," said Pierce. "The one thing we don't want to get to is the point where he's suspended for games. I'm sure a couple of us will talk to him, [because] he's almost as the number and we're not even halfway through the season. Sixteen gets you suspended, so we'll tell him to slow it down a little bit until the end of the season."

Ray-OK

Celtics guard Ray Allen appeared to jam his finger while defending Tony Allen during 5-on-5 drills late in Saturday's practice session. Ray Allen departed the court and was examined briefly by trainer Ed Lacerte, but returned to shoot free throws to close out the session. Rivers said there was nothing to be concerned about.

'He who angers you, owns you'

That's the text message Rivers said he sent a couple players after Friday's game, though he wouldn't confirm if one was Wallace.

"He who angers you, owns you," said Rivers. "I'm trying that this year. If you don't get angry, you can just keep functioning. I actually texted that to a couple guys last night, just hoping that becomes our team mantra right now. Let's breathe.

"Clearly there were some tough [calls on Friday] night, it's not done on purpose. That's what I always say, we just gotta be able to play through it and, at times, we don't. We didn't do a good job of that [Friday] night. We spent way too much time waiting and looking for the officials to bail us out instead of doing our job."

Tony Allen as point guard?

Rivers acknowledged that the absence of Marquis Daniels has affected fellow reserve guard Eddie House the most, since House is now often relied on to carry the ball up the court for the second unit. That's led to diminished returns in House's offense.

The Celtics experimented more with utilizing Tony Allen at the point on Saturday, but that's still a work in progress.

"We're trying to get Tony to handle the ball more, but, when he handles it, we're trying to have him run the team instead of taking it as a play for himself," said Rivers.
