Igor Larionov was born in the United States and played junior hockey in Canada.
He has not played ice hockey so far this season.
"He's a guy we know has a lot of upside, but he will need some time because he has not played for a while.
He and his team have identified Mora as a good place to come to get his career going again and we feel it is an incredible honor, "says Hedberg.
In fact, Larionov's father has also played in the Swedish league system: In the 2005-2006 season, he scored one goal and three assists in two matches for Brunflo IK from Jämtland in division 1.
