The player who tossed his silver medal into the crowd after losing the gold-medal game at the World Junior Hockey Championship was reportedly dealing with a significant injury.
Andersson was in New York City rehabbing his shoulder Wednesday, and he'll likely be out of action for two-to-four weeks, according to the report.
The 19-year-old center is playing this season with Frolunda in the Swedish Hockey League. He served as Sweden's captain at the tourney and was a first-round pick (seventh overall) of the New York Rangers.
