Cowboys defensive tackle David Irving says he will not play Monday night due to a high ankle sprain (Twitter link via Clarence Hill of the Star Telegram). He added that the injury could sideline him for up to four weeks. 
Irving went down in practice on Thursday and tests confirmed that he’ll need a substantial amount of time to heal. It’s a frustrating development for the 25-year-old, who already missed the first four games while serving a suspension and a fifth game while addressing personal issues. So far this year, Irving has only suited up for games against the Jaguars and Redskins, and he could be looking at a half-season of activity when all is said and done.
Of course, this is a key year for Irving as he is slated to hit unrestricted free agency after the season. Last year, after being moved to defensive tackle full-time, Irving showed his potential by finishing with a career-high seven sacks.
So far, Irving has four total tackles on the year including one sack which he recorded in the third quarter against Washington on Oct. 21.
His talent is off the chart but, the Boys need to let him go in the offseason and get someone more reliable.
No, they need to sign him to a cheap 1 year deal and let him produce on a money driven 1 year deal
With teams like the Lions and Jets desperate for a pass rush, the Cowboys won’t be able to retain him on a cheap one year deal.
I do agree with justinkm
Whatever decision the Cowboys (Jerrah) make on this guy, I have absolute faith it will be the wrong decision. In Jerrah we trust!
