Cowboys fear torn ACL for Sean Lee

As soon as Cowboys linebackerSean Lee went down in what was supposed to be a non-contact practice today, the vibes coming out of Dallas suggested that he had suffered a bad knee injury. It’s looking like a season-ending injury.

Although Lee has not yet had an MRI and the team has not announced anything official, multiple reports indicate that a torn ACL is the most likely diagnosis. Adam Schefter of ESPN reports that the Cowboys fear that Lee tore his left ACL, while John Middlekauff of 95.7 The Game separately reports that Lee will likely be out for the entire 2014 season.

Cowboys rookie offensive lineman Zack Martin blocked Lee to the ground at Organized Team Activities. Although it’s not the Cowboys’ biggest concern at the moment, an injury during a non-contact practice may result in an investigation into the team’s practice habits.

The 27-year-old Lee has a long history of struggling with injuries, including tearing his right ACL in college. He has missed 15 games in the last two seasons and has never played 16 games in a season. It’s now looking like he may play zero games this season.
