Injuries: David Irving exits practice with ankle injury

The Dallas Cowboys suffered an injury coming off their bye week.

Defensive end David Irving was carted off the practice field after suffering an ankle injury, NFL Network's Jane Slater reported, per sources informed of the injury. He was listed as officially limited for the session.

According to Slater and NFL Network Insider Ian Rapoport, the initial belief is Irving suffered a high-ankle sprain. Irving's X-rays were negative and he will undergo further testing, per Slater and Rapoport.

Irving missed the first four games of the season due to suspension. He returned to action in Week 6, compiling four tackles and a sack in two games.

If the ankle injury sidelines Irving it would be a noticeable blow to a pass rush that had been hoping to have all its pieces in play for a postseason push. If the fourth-year pro is out for a while, however, it's not like the Cowboys aren't used to not having him available.
