While Colorado Avalanche goaltender Semyon Varlamov remains a game-time decision for Thursday's match against the Ottawa Senators, there are signs that his groin issue may be more serious than first thought.

For one thing, the Avalanche website already lists Varlamov as being on injured reserve. But Mike Chambers of the Denver Post reports that the roster move isn't official yet.

From #Avalanche PR: If Semyon Varlamov does not play tonight he will go on IR. So his slight groin injury could be more than that — Mike Chambers (@MikeChambers) October 16, 2014

So either Varlamov plays against the Senators, or he goes on injured reserve and misses more than one game.

Due to the sensitive nature of groin injuries, don't be surprised if it's the latter and Reto Berra gets the call in Ottawa.
