Well, in a way it's not a big deal.
My C is out for 3 weeks, he earns 94k/week and he's worth 300-350k, therefore I think I'll simply fire him before Monday.
I wish there was another way, but there's simply not enough time to have him available before the playoffs in a decent shape. I doubt anyone would be interested in spending a single $ for him, but still, it would be nice to test the market.
