With Game 3 of the Eastern Conference Final against the Pittsburgh Penguins tied 1-1 midway through the second period, Campbell laid on the ice for a few seconds before mustering the strength to get back on his skates and continue killing the remainder of Boston's too-many-men penalty.
It was a courageous play by Campbell, who grimaced and hobbled through the last 45 seconds of his shift before gliding over to the Boston bench, doubled over in pain. After the Bruins won Game 3 in double overtime, 2-1, to take a 3-0 series lead Boston's players dedicated the victory to Campbell and his never-say-die effort. It was revealed Thursday he had completed that shift with a broken leg.
Boston's players weren't the only people in the hockey world who appreciated Campbell's gritty play.
The day after the heroic turn, some players in the Los Angeles Kings locker room were buzzing about the play as they prepared for Game 4 of their Western Conference Final against the Chicago Blackhawks.
"It's crazy that you hear about a broken leg after and he finishes his shift," Kings forward Colin Fraser said. "We certainly know about him. It's unfortunate to have an injury like that. He doesn't want to be hurt like that and neither does his team. It's crazy, but he's a hockey player."
As word of his effort spread, tributes to Campbell poured in on Twitter.
"Wow. Campbell plays full minute on broken leg. Always respected him, even more now," Asham tweeted before adding the hashtag "#warrior."
It wasn't just current NHL players who were impressed by Campbell's feats. A number of younger NHL prospects turned to Twitter to remark on the play.
With Campbell's season now over due to the injury, more tributes having been coming in on Twitter.
Here is a sample of some of them:
