Sources confirmed to the paper that Backstrom rolled his ankle while training in Helsinki a couple of weeks ago, but aggravated it in the skate.
While the injury is not major and is the opposite ankle from the one he previously underwent surgery on back in April, it will still delay his signing with Dynamo Minsk.
If Dynamo Minsk still has a spot available for Backstrom once his ankle is healed, the netminder could still spend the lockout in between the club's pipes.
In 46 games with the Wild last season, Backstrom registered a .919 save percentage and 2.43 goals-against average.
