Not a joke. From the Pens website:
Penguins captain Sidney Crosby was back on the ice for the first time since missing 29 games with a concussion. Crosby skated on the ice for about 15 minutes in full gear early in the morning at CONSOL Energy Center. He stick handled around some cones and shot a few pucks.
If a "Woooooo" was ever appropriate in any situation, this is the time.
EDIT: We wonder if this was done to shoot down those "retirement" rumors that have been going around. Either way, it's a good thing to hear. Go Sid.
