The Celtics will be without Paul Pierce, Kevin Garnett and Rajon Rondo on Saturday night against the Raptors.

Boston coach Doc Rivers revealed the news during Friday's practice.

Pierce is out with a right knee infection, Garnett with a hyperextended right knee and Rondo with a sore left hamstring.

"We're going to hold a lottery tonight [to determine the starting lineup]," Rivers joked. "We'll put some balls in and see what comes out. We'll have a guard lottery, and a big-man lottery, then like a small forward lottery."
