The extra time should help for sure. He is skating now with the team. I could see it but Finals if they win is more likely
He hopped on the ice for practice before game 6, but he wasn't supposed to be out there. He seems to feel good enough but with concussions you can feel great one day and feel like crap the next. He's basically day to day at this point. If I had to guess, if we win I'd say he's back for Finals.
If they win the finals might be possible but there's no way he's seeing game seven. Not to mention he hasn't played in a month. This is not Superman we're talking about here.
