I'm not sure about John, but concerns me that he says that he "hopes it's nothing serious". Players usually know their bodies so if it's a minor knock he'd know. John's been our best or most consistent player over this last batch of games, even when results have gone against us.
As for Slew, he's out for the season unfortunately -

We do know though that whoever Derek selects will be focused on the job at hand and we've had big players missing/disappear but we've found a way to make it work.
