LOS ANGELES - Don't expect any of the drama afforded Paul Pierce and his knee sprain, but the Celtics have another injury concern in the NBA Finals.

Rajon Rondo rolled his ankle in the third quarter of Game Three on Tuesday and was walking with a slight limp during media availability yesterday at the Staples Center. Rondo said some extensive treatment, plus rest, should get him ready to play tonight. He's not likely to be close to 100 percent, however, and that should force Doc Rivers to play both Eddie House and Sam Cassell a bit more.

"I made a walk around the hotel (yesterday) and I was limping a little bit, but the farther I got, it felt better," said Rondo. "It feels a little better, still sore."

Asked whether he thinks he'll play, the point guard answered, "I think I'll play. Nobody in this league is 100 percent, but I'm sure I'll play [tonight]."

Rondo, like many NBA players, has his own blog (yardbarker.com/rajonrondo) and made the following entry about his status after the game.

"If you were watching the game, you know that I injured my ankle in the third quarter. It happened on a fast break and I rolled it. I think I may have stepped on someone's foot, but I still haven't seen the play.

"It's a different feeling than I've ever had. I've injured my ankle before, but this one is unlike the others. The pain is on the inside of my foot. All the other ankle sprains have been on the outside. I will be getting a lot of treatment [Tuesday, yesterday and today], to try to get it ready to go for Game Four. I did try to go again in the fourth quarter, but I really couldn't make any hard cuts. No one is 100 percent at this point, but I was probably 50 percent. Coach made the right decision taking me out because I didn't have my quickness."

Rivers is expecting Rondo to be ready to go but doesn't want to see him play without his most important skill - his speed. House and Cassell are better shooters than Rondo, but both can be rattled while advancing the ball.

"The problem we had was when (Jordan) Farmar came in. He pressured the ball and we struggled getting into our sets with Rajon off the floor," Rivers said. "We have to solve that, and we can."
