Theory about AJ - has he given up?

[Tomkat]

I have this sinking feeling that AJ is done for the season.
I also feel that even if he was healthy enough to play, he wouldn't, and just
continue to be "injured." Considering the circumstances, I don't blame him. I suspect this could be his "Carson Palmer" moment, but instead of outright protests and ultimatums, he's using injury instead.
