Quick hits from Celtics practice

A view from above the Celtics' practice court in Waltham.WALTHAM, Mass. -- Quick hits after the Celtics practiced Monday afternoon at HealthPoint:

* Green still without Green: Boston remained without swingman Jeff Green, who officially inked a one-year, $9 million contract over the weekend. Celtics president of basketball operations Danny Ainge said the team found something of concern during Green's physical, but stressed that it was not a major concern. "We found something in the physical that we anticipate is fine," said Ainge. "We just have to be real cautious." Asked how long Green might be out, he said, "I don’t think very long. He’s just going through the tests again -- today and tomorrow -- and he should be fine."

* The gang's (almost) all here: Celtics coach Doc Rivers had said that training camp didn't begin until the entire team was on the practice floor. He got his wish on Monday. After three days with less than 10 bodies available for action, the paperwork logjam cleared before the team's afternoon session allowing Brandon Bass, JaJuan Johnson, , E'Twaun Moore, Sasha Pavlovic, Gilbert Brown, and Jamal Sampson to all participate in their first session with their new team.

* Injury watch: Rajon Rondo (right ankle sprain) sat out the session, while Paul Pierce (sore right heel) engaged in the first part of practice before sitting out the end (he was spotted getting the heel massaged at the end of the session).

* The best player on the floor?: Rivers singled out Moore in his practice debut Monday, noting that the "white" reserve team won both scrimmages over the green with Moore hitting the winning shot in one of them. Moore, a second-round pick (No. 55 overall) played point guard with the second unit (with Keyon Dooling shuffling up to point guard with the starters with Rondo out).

* Mid-level exception is gone: Ainge raised some eyebrows when he confirmed that the team had used the tax-payer mini mid-level exception of $3 million to sign Chris Wilcox at the start of the free agency period. There was some speculation that he might have signed at the veteran minimum to join a winning team, but the healthy salary explains his decision to sign so quickly.

* Loose Balls: Players drawing large media crowds included Bass, Johnson, and Moore... Rivers wasn't in any mood to discuss his beloved Chicago Bears getting "Tebow'd" by the Denver Broncos on Sunday... Many of the new faces (and some of the old ones, including Pavlovic, Marquis Daniels, and Avery Bradley) hung around after the session ended to work on offensive and defensive sets with assistant coaches Mike Longabardi and Armond Hill.
