Detroit Lions defensive tackle Nick Fairley, who is having a career year this year, left the game Sunday morning against the Atlanta Falcons due to a right knee injury. The injury occurred in the second quarter of the game when he collided with Ndamukong Suh while pressuring Atlanta Falcons quarterback Matt Ryan. Fairley immediately grabbed his knee and was eventually helped off the field. Once on the sidelines, the medical staff decided to end his day as he could not put much weight on the right leg. He was placed on a cart and taken back to the locker room. There is early speculation that it may be a mild MCL sprain, which would only sideline him for a few weeks. Detroit head coach Jim Caldwell would not elaborate on the injury at all, stating that they do not know any details as of yet but that it looks serious. If the injury is indeed a sprain, the bye week next week will come just in time for him to heal up a little more, missing less time. If it is a tear instead of a sprain, his season will likely be over and the Lions will need to sign someone to replace him. We likely will not get an update though until the team returns to the US and Fairley can be evaluated.
