Ah OK - that's on you. The ProFSL roster is your official roster. If he's down in the minors here, then you should move him to match up the Fantrax roster. When you're ready to call him up, you put a post up here, then you go ahead and move him on Fantrax.
I'll never move players up and down on your Fantrax roster. You can do that at your own will, just make sure you post the corresponding moves here before you do.
