Rasmus Ristolainen absolutely clocks Sidney Crosby early in Game 2

We're only 5 periods into the Battle of Pennsylvania and we've already got the makings of a classic.

After a feisty affair in Game 1, there's been no love lost in Game 2 between the Philadelphia Flyers and Pittsburgh Penguins.

Late in the first period of tonight's action, Flyers defenseman Rasmus Ristolainen took an undisciplined penalty in the offensive zone after he absolutely cracked Penguins captain Sidney Crosby in the mouth with gloved punch.

Come on, Risto...

You have to realize that a punch to the face of Sid the Kid is going to warrant a penalty all day, every day. Undisciplined play by the veteran blueliner.
