Indians outfielder Grady Sizemore is headed back to the disabled list. He is dealing with a bruised right knee and has already been on the disabled list twice this season. Sizemore was sent back to Cleveland to have tests done on his knee before making any estimates about how much time he will miss this time around. "The way he plays and the way he goes about his business, he goes hard after it," Indians manager Manny Acta said. "You've got to respect that. He's not going to be taking it easy just to get healthy."
