Gagne, 29, potted 34 goals and picked up 40 helpers for 74 points last season for the Flyers, and ranked second on the team in goals, third in points, and third in plus/minus.
Tim Pannacio tweeted that he appears to have re-injured his hip in which he had surgery on this offseason.
The extent of the injury is not known, however if it is serious this could be a disaster for the Flyers, who have already lost 52 goals this summer. The NHL told teams a few weeks back not to honor any contracts of players injure during Olympic training camp.
Jeff Carter, Chris Pronger, and Mike Richards are also attending the camp.
This is why I don't like having professionals playing in the Olympics because these players are under contract with their NHL teams, and if they can injured playing in the Olympics, the team has nothing they can do.
Reports say that it isn't his hip, and that he injured his groin. It is also believed not to be serious, but with groins, you just never know.
