The Celtics' ship was sailing without its captain on Wednesday, as Paul Pierce was absent due to illness.
Pierce joined Shaquille O'Neal (inflamed Achilles), Jermaine O'Neal (left knee surgery), Marquis Daniels (bruised spinal cord) and Semih Erden (right adductor strain), who were all missing from the workout.
"We don't worry about body count. [The Lakers are] not going to worry about the body count, I can guarantee you that. We'll be ready, we'll be fine," Doc Rivers told ESPN.com. "Size will come into play at some point [Thursday], but, listen, we have what we have. We're going to line it up against whatever they have and see who wins the game."
"We just gotta get it done," Glen Davis added. "Things happen, players get hurt. You gotta keep going. That's why you have 15 people on the roster."
