Logan Morrison is sidelined again after he experienced swelling in his surgically-repaired right knee Wednesday following his return to action Tuesday. Morrison says he's not in any pain, but he has to "get the swelling out of there for it to heal." The Marlins and Morrison don't seem concerned at this point that the outfielder's availability for Opening Day might be in doubt, but if the swelling in his knee remains much longer, it would seem to be a possibility. "I'm not trying to think about any of that," Morrison said when asked about possibly missing Opening Day. "If I think about that, I might kill someone."
