That's a relief! Hopefully he will be able to contribute near his usual level of production, although I'm still doubtful you can recover from a concussion so quickly... but I don't know much about it, though. 
It depends on the severity, which we never got an update on. IF it's just a minor concussion, which can knock you loopy like we saw but not result in any swelling, he should be good to go.
IF it' a higher grade concussion...I hope he takes it easy.
Of course, one assumes if it was a bad one, the doctors would override him and sit him down for safety's sake.
LETS GO C'S!
