Mark Prior is having elbow problems, and will likely miss his next start.
Trainer Mark O'Neal notes this is NOT the same problem that affected Prior last year:
I will reserve judgment until I get more information.
As if that's enough, non-roster invitee Dave Hansen had to have an emergency appendectomy, and will be out three weeks, which would be Opening Day, and that would pretty much kill his chances of making the club -- unless they want to offer him a slot at Iowa while he gets his strength back.
Wherever this cloud of injuries came from, I hope it clears up soon.
