A short-term illness like the flu that was exacerbated by altitude sickness?
If it was that, they would just say so. In fact, i'm not sure why they didn't say it was that even if it wasn't.
They are not averse to saying what Saad has right now is flu-like:

Forward Brandon Saad missed practice on Thursday because of a stomach flu-like symptoms and did not make the trip.
“We just don’t want it to be contagious,” coach John Tortorella said, “so he will not be playing (tonight).”
Instead, we got multiple quotes from Jarmo, Torts, Cam, etc saying they didn't really know what was wrong with Joey while he was away.
I don't believe in big conspiracies, but I also don't think Occam's razor points to the flu as being what was wrong with Joey in this case.
