Many hope that Sidney Crosby's injury that put him on the sidelines in January will bring about major changes to the official hockey rules.
Khatja Westbrook of Mount Royal University says that results of medical studies that show the impact of concussions don't always trickle down into normal life.
She does think that Sidney Crosby's celebrity status will make some major headway, but any change will likely take years.
"The most high risk plays are the hits from behind, the dirty plays, the ones that should have got penalties. In the first place, for those to be enforced and be enforced all the time - that's when you're going to start to change behaviour," Westbrook says.
Hockey Canada had already adopted a zero tolerance policy in terms of hits to the head, but there are people who are looking for more.
Darren Lane, a minor league hockey coach, has seen his son suffer three concussions and Crosby's injury is just one more reason he wants to see changes.
"I think the biggest thing that should happen is we should take hitting out of all levels, expect maybe the top two or three levels of elite."
The University of Calgary undertook a massive study of NHL concussions between 1997 and 2004 and found a concussion rate of 5.8 for every 100 players or just under two concussions per 1,000 player hours.
Hockey Calgary has stopped hitting at the Peewee level, and safety procedures are constantly being reviewed.
Perry Cavanagh, past president of Hockey Calgary, says the rule isn't a new initiative just because Sidney was hurt.
"It came five years ago. We've been fighting the battle and won't stop until we know what's been done is right here for the kids in the city of Calgary."
New rules about physical contact won't only be for hockey. Other sports like rugby and soccer are looking at making changes to the way they play.
