With the spasms and much of the pain gone, Rockets guard Jeremy Lin remains optimistic he will return from his bruised right chest muscle in time to play Saturday in Game 3 against Oklahoma City.

But he has learned not to make guarantees.

“Not going to make any promises or anything,” Lin said. “I just don’t know. Right now, it’s just day-to-day. I’m still hopeful, still optimistic. I just learned my lesson about making guarantees.”

Last season, Lin kept expecting to return from his knee injury but never did and missed the New York Knicks’ playoff series. This season, he has not missed any games despite some ankle sprains.

After making significant progress since the collision with Thabo Sefolosha that forced him to miss the second half of Wednesday’s Game 2, Lin still had to regain the strength in the muscle needed to play.

“It feels a lot better,” Lin said. “Tomorrow we’re going to work on some more stuff. Today was all range of motion. Tomorrow will hopefully be some jumping. And we’ll go from there. … This is something that should heal quickly. I’m not there yet. I don’t know when I will be.

“The worst part was the spasming. That’s gone now. Now it’s just getting range of motion and getting pain free. I can’t shoot today. … Right now I have range of motion, but I don’t think I had any force.”Positive attitude, officiating aside

Forward Greg Smith said the Rockets emerged from Game 2 with a positive attitude, which is more than can be said for Smith’s attitude about the officiating Wednesday in Oklahoma City.

“We’re a hard-fought team,” Smith said. “We knew (the Thunder) had the refs on their side, that they had the home-court advantage, so we just came out and played hard. Coach (Kevin McHale) said to keep fighting, try to get the win, and we fought, we made shots, played good defense. We started playing zone, and they didn’t have the plays to beat that.”

The attitude during Thursday’s team meeting, Smith said, was, “That game was ours. We had great effort. We played good, had good spacing. … Everything was positive.”

Even though the Rockets’ smaller lineup limited his minutes, Smith thought it was a good idea because it drew Thunder forward Serge Ibaka away from the basket and limited his shot-blocking opportunities.

“Anything for the team to win right now, I’m for it,” Smith said. “If my minutes are the same or lower, I don’t care about myself. … It seems our four guards, one big is working, and I would like to continue to do that.”
