Not good news.
Update: Apparently it is a right index finger strain, which doesn't sound overly serious, I wouldn't think he should be out longer than the 15 days.More Updates:
Ummmmm if something went 'pop' it isn't a strain'
Morrow felt something pop in his right index finger last night. He's on the DL and currently in Arizona getting an MRI. #BlueJays— Gregor Chisholm (@gregorMLB) May 3, 2014
