Indians outfielder Grady Sizemore is day-to-day with a sore right knee. The team breathed a sigh of relief on Wednesday night when tests came back clean and showed no structural damage. It's also good news that the injury is unrelated to the left knee issue that kept Sizemore out for a majority of the 2010 season. "Our medical staff doesn't think it's anything serious," manager Manny Acta said of the tests. "It was scheduled from [Tuesday] just to give him some peace of mind because of what he's gone through with the other knee."
