He has been suffering from this injury for about three weeks but the pain was getting increasingly worse to a point that the only way he would heal is to be left out of the game.
He played Friday night when the Oilers took on the Anaheim Ducks. He even scored the winning goal for his team. Though concern took over when Ference was scratched the following game during a 5-0 loss to the New York Rangers.
When the pain was getting worse they sent Ference for an MRI and found the slight tear. Coach Dallas Eakins has already said this is not a 'day-to-day we will monitor' situation and instead it is a 'week-to-week' situation.
So far this season Ference has three goals and fifteen assists while averaging around 20 minutes of ice time per game.
