As we said on Twitter, all we can do is hope that he's ok. He's earned it.
We talked on our podcast earlier this week about how Sid is a "moments" guy. He's more prone to seizing the big moments than he is to sustained excellence over long periods of time (he'd obviously do both if he didn't have so many "concussion-like-symptoms," whatever that means, over the past year). With this knowledge of Sid, our expectations for his return differ from our hopes for his return. We expect him to score 4 points or get another concussion.
If we had our druthers, he'd play 16 minutes, have a power play goal, and escape MSG unscathed. But that's not how he rolls.
