Scary moments early in the game. Defenseman Dan Boyle of San Jose was taken off the ice in a stretcher after being checked from behind by St. Louis’ Maxim Lapierre, who was ejected. A Sharks spokesperson said Boyle was alert and responsive and will be held overnight for observation at the hospital

“No one in their right mind would ever want that to happen to another guy,” said Blue captain David Backes. “Our thoughts and prayers are with Dan Boyle and his family. That’s a scary thing, it’s something you hope never happens. Hopefully he has a speedy recovery and he’s back on the ice soon.”

Several Sharks players thought the play was dirty, including Logan Couture. “It’s just disgusting to see that type of play in hockey, when a player that probably shouldn’t even be in this League is taking out one of the best players in the world,” said Couture. “Lapierre has got a history.”
