Dwayne Hay, Georges Laraque, Steve Moria and John Haig are amongst the players already confirmed as taking part in the event, with many more to be announced over the coming weeks.
CHAS is the only charity in Scotland that provides vital hospice services for children and young people with life-shortening conditions.
StopConcussions has been designed to educate players, administrators, physicians, coaches and officials on the cause, effects and consequences of concussions and neurotrauma injuries, not only in hockey but all sports.
Organiser Neil Webster is aiming to raise at least £3,000 and he hopes fans will come out in force to support the event.
“I’ve been watching ice hockey all my days – my uncle was with the Fife Flyers and I was fortunate enough to play in a charity match over in Canada,” Webster told the Dundee Telegraph.
“That was incredible – it gave me the inspiration to want to do something similar here.
“We’ve got three guys coming over from the NHL and, with the Scottish Alumni, we’ll have some legends of the game — the likes of Grant Slater and Jock McGuff — so we’re really trying to get people through the door to see them.
“There’s a really nice mix of talent involved and we are hoping it can help us to raise as much as possible before, during and after the event for a brilliant charity.
“CHAS are outstanding in what they do and we’re trying to do as much as we can around the event to make a difference.
“It promises to be a great occasion. Come along and see a clash of legends on the ice and, better yet, get involved!”
The game is scheduled for Saturday, 19th August, at Dundee Ice Arena. Please click here if you wish to make a donation.
