The Dallas Cowboys offensive line has been solid the last few weeks in training camp even without Zack Martin around.

Thursday, the depth may have taken a hit, though.

Chuma Edoga who was slated to start the season as the backup left tackle behind Tyron Smith went down.

Edoga appeared to suffer a knee injury and was carted off the practice field.

A video from those at camp covering the team Video showed Edoga, the 26-year-old signed by Dallas in March, lined up at left guard on the play.

He was eventually hit below the knees by a falling Jabril Cox, who had met ballcarrier Hunter Luepke coming through the hole.

Even if he wasn't a starter, this hurts the depth of the offensive line that for the first time in a few years looked to have a lot of it.

Tyron Smith has looked really sharp in camp, but Edoga would have been a solid guy to step in if Smith went down again.

This injury may not even be anything, and he could be fine tomorrow.

Michael Gehlken of the Dallas Morning News noted on Thursday afternoon that the initial belief is that Edoga hyperextended his right knee.

Thank goodness.

Looking ahead

This is why I don't want the starters to even play in the preseason games.

You never know when something like this is going to happen.

The Cowboys play their first preseason game this afternoon against the Jaguars.

Most of the starters will probably sit, but Doug Peterson said his squad will be playing most of their starters for at least part of the game.

Look for guys like Josh Ball and others to take snaps on the offensive line.

Edoga was slated to start the game this afternoon

I really like the state of this team.

We will see how they do when the games count in September, but as long as they avoid any other scares like Thursday, they should be awesome.

Martin is still a question mark.

He will probably hold out until week one against the Giants in September.

The future Hall of Fame guard doesn't need training camp anyway, but!

When you think about it. He is a LEADER of this team.

A guy everyone looks up to, and he's not there.

He does deserve what he is asking.

Martin's per-year average of $14 million is just eighth on the list of guards across the NFL.

The next few weeks are going to tight.

Let's hope they get through the four games of preseason with no major injuries.

This season is going to be fun, and I am so ready for opening night.
