One minute I am hearing "Just a shoulder sprain" (which IMO is still a big deal since it's his throwing arm), the next that he's in a great deal of pain still and is having a second MRI done today.

It's sounding more like he's out for at least a couple of weeks, maybe more. But, as you all know, the wind is blowing back and forth right now on the issue. A bit of information/disinformation, not to mention sensationalism going around. But, adding all of what we are being told up, it doesn't look like he's suiting up sunday night.
