LOS ANGELES -- Dodgers third baseman Casey Blake missed his second game and underwent an MRI exam on his sore lower back on Friday, but he believes the injury is relatively minor.
"No, I'm not worried," said Blake. "I think it will be a couple of days. Either it'll be a lot better in 48 to 72 hours, or it might be a lot slower. We should know a lot in the next day or so."
Blake said he had not yet received results of the MRI, but doctors were encouraged that he had no leg symptoms, which often is a sign of a disk problem.
"But it's also something you can't really play through, because it can get worse," he said.
Blake said he felt a grabbing after fielding a ground ball and preparing to throw during infield drills before Thursday night's game. He said he's never had a serious back injury.
Meanwhile, reliever Jeff Weaver said he was taken out of Thursday night's game after warming up on the mound because the skin had separated beneath the corner of his middle fingernail while warming up on Wednesday and Dodgers manager Joe Torre didn't like the way Weaver was warming up.
"It's something I could pitch with, but it's very tender and kind of burns a bit when I throw," said Weaver. "I was fine, but obviously they didn't like what they saw in warmups. I feel I can deal with things other people can't. I had no problems going out there throwing. If I have a chance to not pick up a ball, it's something that will heal quickly."
