Just when it appeared everything was falling into place for the beginning of what is supposed to be the Warriors' breakout season, one of their most important players is limping out of the gate.

Shooting guard Jason Richardson missed his second straight day of practice Tuesday with a sore left knee and might not play in tonight's season opener against the Atlanta Hawks. Richardson said his knee has been bothering him throughout training camp but got to a point last week where he could "barely walk."

That being said, Richardson said he will be in the lineup tonight.

"I'll play," he said after Tuesday's practice. "I've worked too hard this offseason not to be able to help my teammates. I just have to take a couple of precautions."

While Richardson said he is playing tonight, Warriors coach Mike Montgomery wasn't so sure.

"It will be a game-time decision," Montgomery said. "His knee hurts. If he can't go or be effective, he can't play. If he's not effective, we're better off not going with him."
