"There's constantly criteria that you need to think about," said Campbell, the NHL's former head disciplinarian. "I'm not new to this location. It's been a while, but I did suspend over 450 players over 14 years.

"I've heard every possible factor why a player did what he did."

Capitals general manager Brian MacLellan called the situation "unfortunate."

"It's a psychological response [by] a player that got caught up in it and had a couple men coming after him," he said." [Hathaway] reacted, admittedly, in the incorrect way. We'll see what takes place."

Calvert fallout

The Colorado Avalanche were left fuming Saturday when Matt Calvert was hit in the head from close quarters blocking a shot versus the Canucks. On-ice authorities permitted the play to continue as blood spilled from Calvert prior to Vancouver scored minutes later.

The guideline book states referees might-- but don't need to-- blow the play dead when a player is seriously hurt even if his group does not have the puck.

"It appeared like an eternity in that game, despite the fact that it was closer to four or five seconds," stated Walkom, a previous referee. "The puck was moving around, the guys were inspecting, the player attempted to get up.

"Of course we would have liked to have blown the play down previously."

"It was a tough one," Campbell stated."Our guideline book's quite tight," he said."There's always criteria that you have to consider," stated Campbell, the NHL's former head disciplinarian."Look no further than why a goalie can't have a warmup-- coaches are competitive and they took the rule and they used it as timeout," he stated."Sometimes you get it right," he said.

While it certainly wasn't the case in this circumstances, Campbell said the league is constantly cautious of players and groups decorating to get an edge.

"Look no even more than why a goalie can't have a warmup-- coaches are competitive and they took the guideline and they utilized it as timeout," he stated. "It's no various when a player embellishes an injury.

"It's a judgement call."

Arizona Coyotes GM John Chayka said he doesn't think a guideline change is needed to avoid comparable circumstances in the future.

"Those are difficult," he stated. "No one desires to see a gamer [get harmed] like that. The basic consensus was if there's a situation like that once again and they recognize that's the circumstance then certainly blow it dead."

Tallon agreed, including the on-ice officials need to use typical sense.

"Sometimes you get it right," he stated. "The intent of the guideline is to ensure someone's not [staying down] purposefully.

"But because circumstance, all of us agree there need to have been a quick judgement there."
