I know that he's out "indefinitely" according to the team, but really, how much can be known until he gets his MRI results back? If he's out four to six weeks, then you drop him if you need the roster spot. If he's out longer, you drop him no matter what. What if it comes out better than expected, though? The bye is next week, and perhaps he only missed one game? If that's the case, I'm keeping him rostered for certain. In leagues of at least moderate depth, there's likely not anything better on the wire.
