An X-ray on Matt Cain's right forearm came back negative. He's been diagnosed with a right forearm contusion as a result of a line drive that caught him during Thursday's start against the Pirates. While the news is good, Giants manager Bruce Bochy said it's too soon to tell whether Cain will make his next start. "We're not going to take any chances, I'll say that," Bochy said. "He's going to have to have a tremendous recovery and not feel anything."
