San Jose Sharks defenseman Dan Boyle was alert and responsive on Wednesday after he was was knocked into the boards and left the ice on a stretcher in the first period of Tuesday night's game against the St. Louis Blues.
"Sharks defenseman Dan Boyle was kept overnight at a hospital in St. Louis," the team said in a statement on Wednesday morning. "He will be returning to San Jose later today to continue his medical care and undergo further evaluation."
Boyle told the San Jose Mercury News in a text message that he was recovering.
"I'm OK. That was scary," he said. "Hopefully, the symptoms will be very minor if any going forward."
Boyle was hit from behind by St. Louis' Maxim Lapierre with a forearm check and was sent face-first into the left corner boards while trying to retrieve the puck. Boyle remained on the ice for several minutes before he was carted off.
Lapierre is suspended until the league conducts a review of the hit. Reports indicated that he was offered an in-person hearing on Friday, which suggests that the suspension could be six games or longer.
Lapierre was ejected from the game and penalized five minutes for checking from behind. He also received a fighting major.
It's uncertain how long Boyle, the team's top defenseman, will be sidelined.
The Sharks defeated the Blues 6-2 to remain unbeaten this season at 6-0.
