Boston Celtics Rasheed Wallace and Rajon Rondo, both of whom are nursing back injuries, participated fully in Wednesday's practice session, including contact drills, a positive sign as both ramp up for Game 1 of the NBA Finals on Thursday.

Wallace, who originally tweaked his back during Game 5 of the Eastern Conference finals against Orlando then left in the fourth quarter of Game 6, had been held out of contact drills earlier in the week, but moved fluidly in the portion of practice open to the media, which included stretching and shooting drills.

Rondo said he'll be near full health by Thursday.

"My body is fine," said Rondo. "These five days have definitely been great for me personally. I know it's great for the team, but for me I've been getting a lot of massages, a lot of treatment. I'm feeling better and better each day. The more time I get, the better I am. [Thursday], I'm sure I'll be back almost at 100 percent."

Elsewhere on the Celtics' injury front, Marquis Daniels (concussion) said he is feeling better, but is still waiting full clearance from trainer Ed Lacerte.
