I may've gotten it the wrong way around - I remember reading something about 10 day contracts, and I thought it was that teams could no longer sign players to them, they need to sign for the remainder of the season. But, perhaps I read that 10 dayers are now available, as opposed to closed.
Either way, I doubt he'd fly out there for a 10 day contract (or 2). I'd suggest he'd be at least getting guaranteed coin for the rest of the season. He'd likely get the minimum pro-rata for the amount of time he's there.
