The Cowboys have had one of the NFL’s more formidable front sevens over the course of this season and have done so with a defensive line that’s been one of the league’s best.

Surprisingly, that line group hasn’t included David Irving. The Cowboys poached him from the Kansas City Chiefs practice squad back in 2015, and ever since then it’s been an up and down road with him regarding off-the-field incidents.

A report from Mike Fisher on Friday gave insight into the latest details on David Irving as far as the Dallas Cowboys are concerned. According to the report, Irving has missed multiple drug tests over the last two months (misses count as failures) as well as all sorts of team-related activities and functions.

Dallas Cowboys defensive tackle David Irving has missed “multiple’’ mandatory drug tests in the last two months, sources tell me, putting in jeopardy not only any chance he has of participating with this team during the NFL Playoffs but also his chance of playing in the league anytime soon.
