If he is injured, they would have to carry him on the major league disabled list, so he can't be injured too much.

A strange game being played.

Maybe he will sneak thru. Seriously, is he ready to pitch in the majors out of spring training? Better to sit back and watch him pitch in the Twins minors and have them need to make a decision, or let him walk, after this summer.

He would be a minor league free agent after this season.

I don't understand the reasoning or the motivation behind a move like this, but Chargois is a guy I would hate for the Twins to lose. He looked great 2 years ago.
