Jordy Nelson, a Super Bowl winning wide-receiver with the Green Bay Packers will miss the entire 2015 season with a torn ACL. There was no contact on the play, which occurred during the second pre-season game of the year for the Packers. Pre-season competition is a valuable way of mentally, physically, and tactically preparing for an upcoming season. With any exposure to high-intensity competition comes the risk of injury. In the NFL, pre-season injuries like Nelson’s are common. Of the injuries sustained, ACL tears are one of the most common. 132 ACL tears have occurred since 2013: 25 of them occurring this year, and 10 occurring during pre-season play (1).
