BOSTON -- Sharks defenseman Dan Boyle is not ready to forgive St. Louis Blues forward Maxim Lapierre for the nasty hit that drove Boyle face-first into the top of the boards and knocked him unconscious.

"He left a message. I think it's been documented that I didn't take the call," Boyle said Thursday. "I'll leave it at that for now."

Boyle had just come off the ice at TD Garden after his first practice since the head injury that has sidelined him the past four games and was willing to talk about the hit, its consequences and the progress he's made. Just not Lapierre.

Neither the Sharks nor Boyle would set a timetable for his return to the lineup. Boyle said he hopes to play on the current trip.

Maxim Lapierre #40 of the St. Louis Blues checks Dan Boyle #22 of the San Jose Sharks into the boards at the Scottrade Center on October 15, 2013 in St. Louis, Missouri. Boyle was injured on the play and had to leave in an ambulance.

Boyle started to describe it as a concussion, then backtracked.

"With concussions, you have to be careful. I haven't actually been told that I've officially had one," Boyle said. "Still kind of waiting on more results from the doctors and more feedback on what they saw."

He had no memory of the play.

"I remember stuff that happened before and starting the game and a couple things that happened in warm-up," Boyle said. "I remember being in the ambulance. I don't remember being carried off the ice."
