More bad news for the 3-8 Cowboys. On Friday, head coach Mike McCarthy announced that offensive linemen Zack Martin (calf) and Cam Erving (knee) will miss multiple weeks. 
Both players were injured during the Cowboys’ blowout loss to the Washington Football Team on Thursday. Martin has been playing through the calf injury for weeks and aggravated it while on the field. Erving, meanwhile, was forced out on the Cowboys’ first drive of the game.
Even in the woeful NFC East, the Cowboys aren’t likely to see the playoffs this year. Even if the linemen can return before the year is through, the Cowboys might keep them off the field as a precaution. Terence Steele took over for Martin while Brandon Knight subbed in for Erving — they’ll likely be first-string for the time being.
On paper, the Cowboys were set to return one of the league’s very best offensive lines. Unfortunately, injuries to left tackle Tyron Smith, right tackle La’el Collins, and center Tyler Biadasz have decimated the unit. Biadasz may come off of IR in a few weeks but, similar to Martin and Erving, the Cowboys will have to weigh the risk vs. the limited reward.
