Henderson Alvarez experienced discomfort in his throwing shoulder following Sunday's rehab appearance. His return is now put on hold. He was previously expected to join the A's rotation as soon as this week. (The Sacramento Bee)
Alvarez was nearly back to full-go, so it's unfortunate to see the injury take place at this stage. It's unclear how much more time he'll require, either shut down entirely or more time in the minors rehabbing. More should be known on his status this week, but his return would not appear to be pending considering the discomfort.
