EL SEGUNDO, Calif. -- After sitting out the Finals opener Thursday still feeling the effects of the concussion he sustained in Eastern Conference Finals in Orlando, Marquis Daniels could be available for Game 2 tomorrow night.

Daniels ran through practice today at the Toyota Sports Center in El Segundo for the first time since colliding with the Magic's Marcin Gortat in Game 5 of the conference Finals.

Immediately following that loss, Daniels was visible dazed in the locker room, but today, he was on the floor shooting during the media session, saying that he felt no headaches or any other lingering effects. Before Game 1, he arrived at Staples Center almost at the same time as Ray Allen, working out and getting shots up.

But Celtics coach Doc Rivers held him out.

"I feel good," Daniels said. "We’ll see. Hopefully, I’ll get to go. I just want to try to be ready and come in and do whatever [Celtics coach Doc Rivers] needs me to do."

Coming into the series, Rivers wasn't uncertain about whether Daniels would be able to play in any of the games.

"Marquis I think is going to be okay," Rivers said. "We're hoping. We'll know tonight, today. We're going to practice and we're going to make him go through live, so that's a big surprise for us. That's good for us. We didn't think that ... I thought he was out for the playoffs personally, so that's a good thing. I can't guarantee tomorrow, but I think there's a good chance.”
