With respect to the IR stuff, yahoo can't do anything until the team actually puts them on to the IR first. If Atlanta doesn't make the move, yahoo won't either. There's never really a clear explanation of why a team does or does not, though there is some suggestion it relates to salary cap issues.
Gonchar for example isn't on IR even though he's now been out for a week and still not on IR, not that it makes a bit of difference for me as I have no room in the Inn anyway (I'm actually pleased with his injury, if that's possible, because he's still skating in practice so should be in game shape when he returns). But the same happened with Sedin as he sat out for about a week with a broken foot and wasn't even listed as DTD. Souray at least made sense as they didn't know how long he'd be out because concussions are notoriously hard to diagnose.
Sorry for your loss on Kovy, but if you have any IR questions, I can probably answer them.
