Alfonso Soriano went for an MRI on his left knee Saturday after having problems in the field on Friday. Soriano had been hoping to push the MRI back until after the weekend and will likely get a cortisone shot to relieve the pain if he doesn't have serious damage. "It's something that needed to be done, so the quicker the better," Cubs manager Lou Piniella told the Associated Press. If Soriano has a cortisone shot, Piniella claims that he could play by Tuesday.

Reds starter Aaron Harang has undergone an emergency appendectomy and will miss the remainder of the season. "It's kind of been our year," manager Dusty Baker told the Associated Press.

Harang is the ninth Reds player currently on the disabled list, and the fifth from their Opening Day roster.

Dodgers pitcher Hiroki Kuroda suffered a concussion when he was hit in the head by a line drive during a 4-3 loss to the Diamondbacks on Saturday night, but tests revealed no fracture or internal bleeding, according to an Associated Press report. ?Amazingly, things look really pretty good,?

David Wright sustained a concussion after being hit squarely in the helmet by a 94 mph fastball from Giants starter Matt Cain on Saturday, and the Mets third baseman was expected to spend the night in the hospital, according to an Associated Press report.

Beltre is out indefinitely and manager Don Wakamatsu told the Seattle Times that he could need season-ending surgery for a bleeding testicle. "It hurt pretty bad," Beltre said. "It was hurting me pretty much the whole game after that." He doesn't wear a protective cup because he finds them uncomfortable.

Cubs third baseman Amaris Ramirez received a cortisone shot in his injured left shoulder on Tuesday. He hopes to be back in the lineup for Chicago by Friday. "I have a pretty good idea of what I can tolerate," Ramirez said of the pain, according to the Associated Press. "In Colorado I tried, but I couldn't do it. It was too painful. But I don't want to miss any more games. I've already been out of the lineup enough."

Chad Billingsley will miss his scheduled start against the Giants on Wednesday with a strained left hamstring, according to an Associated Press report. Billingsley left his last start against the Braves after straining his hamstring on a single. He threw on the side before Monday?s series opener against the Giants and still felt the tightness so the Dodgers decided to skip his next start. ?I don?t view it as a setback,? Billingsley said. ?Being only two days and being able to throw almost 100 percent, I?m happy with that.?
