Duffy is no longer experiencing shoulder discomfort, but the status of his next scheduled start Tuesday remains up in the air, Andy McCullough of the Kansas City Star reports. Duffy was removed from his last start Saturday after just one pitch, but received some good news Tuesday when an MRI came back showing no structural damage. He has yet to play catch since suffering the injury the injury, however, and remains uncertain as to when he'll be allowed to throw again. Duffy had originally anticipated only missing one turn in the rotation, and if this notion is going to hold true, he'll need to throw a bullpen session by Sunday.
