The mere mentioning of the word "rehab" suggests is might be several different things. Could be drug related, mentally related or even physically related. Since his 4-game suspension was reported to be drug related, it seems a real possibility that that's your clue #1. If it's physically related, the media term wouldn't be rehab -- it'd more than likely be "conditioning." If it was mentally related, seemingly, the term should properly be called "psychiatric evaluation." Take your pick . . .
David Irving may or may not be headed for release at some point in the future, although I'm inclined to suspect the FO and the staff will choose to keep him around this year as one who should prove useful as a part of the DL rotation. In the meantime, Jihad Ward is making the most of the opportunity that was afforded him by way of Irving's suspension and the subsequent "rehab" to follow.
Whoa! Seems like things are getting more intriguing by the day!
