I know there is not official injured list, but the official nba site has him listed out injured for the next 2 games....they even have a return date!
This doesn't seem overly difficult if you're paying attention yahoo?
If player is going to miss less than 1 week of play, they don't qualify for the IL.
Well, then they need an IL+ designation similar to IR+ in yahoo fantasy hockey...it covers OUT, DTD, etc.
Bottom line, if a player is out even 1 game for whatever reason, you should be able to IL/IL+ them and use an "add" if available.
