Giroux: he doesn't have one, according to his agent, Pat Brisson, who spoke to CSN Philly:

“There is nothing wrong here, Claude is doing great,” Brisson said from his office in Los Angeles.
“I don’t speak lightly. I’m not one of those who would speak from one side of my mouth.”


Giroux has been in Atlanta getting treatment on his neck from the same doctor who treated Sidney Crosby's concussion. Giroux injured his neck a few weeks ago in Germany and it was feared to be a concussion. It now appears that it's not serious. Carry on.
