The slash delivered by P.K. Subban to the hands of Mark Stone's in Game 1 may jeopardize the rookie's availability for the remainder of the Ottawa Senators' first-round series with the Montreal Canadiens.

Stone was the recipient of a Subban two-handed slash across the wrist in the second period. Subban received a five-minute major and a game misconduct for his efforts. However, the NHL Department of Player Safety announced Thursday morning that it would not pursue supplemental discipline on Subban.

Sens general manager Bryan Murray called the league's decision not to suspend Subban "disturbing".

"There were two attempts on faceoffs to slash him, one connected. Then he two-handed him across the wrist in front of the net," Murray said Thursday. "It’s a huge loss that even if he can play limited at some point in the series, it’s a huge loss to our hockey team. It was disturbing to me that [the Department of Player Safety ruling] was released this morning."

"I gave information to the (series) supervisor last night what I had been told by the doctors," Murray added. "We knew before the game was over that he was trying to play hurt, that there were obviously after-effects. It was released that Subban would face no additional punishment. I thought the referees made the right call on the ice obviously. But I thought also after knowing the extent of the injury that something further should be considered." 

The Senators tweeted Thursday morning that the rookie sustained a microfracture on his right wrist during Game 1 on Wednesday night.

Subban also spoke on Thursday and said he did not threaten Stone prior to the slashing incident.

"I've never threatened anybody out there, I don't think I would. First of all i'm not the toughest guy out there without my gloves on. In not really going out there looking for fights or anything like that. I just try to play the game hard between whistles," said Subban.

Subban also said that he doesn't plan on reaching out to Stone regarding the slash. He did admit that he felt the referee made the right call on the play.

"Obviously it's frustrating when you get kicked out of the game but if I was to comment on the officiating, the ref made the right call," said Subban. "When you see a player down on the ice rolling around like that, there's one call to be made and he made the right call." 

The 22-year-old Stone returned to the game later in the period but appeared to aggravate the injury later in the game.

Stone's status for Game 2 remains doubtful, but Murray stated that a return was not entirely impossible.

"I would assume [Stone is out], but I think the trainers have worked on him and tried to do things. Mark is willing to take shots and whatever it is, but he has no mobility at this point at all."

Stone led all NHL rookies in scoring this season, registering 26 goals and 38 assists in 80 games.
