The Dallas Cowboys might be without one of their offensive lineman if right guard Zack Martin misses any time with a knee injury that kept him out previously this season.

The Cowboys have been playing as good of football as any other team as of recently and they have now won five straight games after beating the Super Bowl Champion Philadelphia Eagles on Sunday. The Cowboys have been known for their elite level offensive line for years now, dating back to when former NFL running back DeMarco Murray.

The Cowboys desperately need Martin going forward if they hope to keep their playoff hopes alive. Dallas' offensive line has been provided the cohesive aspect of the team's offense and without players like Martin, the offense will surely suffer.

With three games left of the regular season, it's going to be crucial for Martin to get healthy for playoffs considering at this point it appears that the Cowboys have no intentions of slowing up. The Cowboys do have some depth on the offensive line, but Martin has proven to be irreplaceable for many seasons now.

Dak Prescott and Ezekiel Elliott would likely have to adjust to high degree if Martin misses any time and in turn, the receivers would suffer a bit as well. That's simply the kind of player Martin is, his presence on the field has been able to keep the offense gelling this season. It would be dramatically different without him since they are already without fellow lineman Travis Frederick.
