Diamondbacks right fielder Justin Upton jammed his right knee on Sunday while tracking down a ball. He left the game immediately, but the injury appears far from serious. "It's going to be sore," he said, "but I don't think it's anything. It shouldn't be too crazy." Upton says he wasn't worried when the injury occurred. "No, no, no. I didn't hear any cracks or pops, nothing like that," he said. "But it was definitely something that needed to get looked at. I'll come in (Monday) and get examined, and as of now I'm just going to play it by ear."
