IRVING, Texas – There isn’t a spot on the team more in shambles than at linebacker.

Earlier in the season, it was the defensive line, a position that has seen nearly 20 different players take the field at some point.

But it’s never been as bad as it was, or is right now, at linebacker.

What the Dallas Cowboys finished with Sunday against the Packers should be worse than what they will play with this week in Washington. The main reason for that is the availability of Bruce Carter, who all but guaranteed he will play this Sunday, despite missing last week’s game with a hamstring injury.

Not only playing, but Carter is expected to wear the defensive headset in his helmet, something the Cowboys played most of the second half without last week against the Packers. Carter will make the defensive line calls despite staying at weak-side linebacker.

That means DeVonte Holloman, a rookie who had missed five straight games until last week with a neck injury, and a player who played both outside linebacker and safety in college, will be the Dallas Cowboys starting middle linebacker this week.

Holloman has played other positions before in his collegiate and high school days, but never in the middle. He’ll get that shot Sunday with perhaps the season on the line for the Cowboys.

So what’s the hardest thing for Holloman?

“Knowing what to look for before it happens. Guys have been in the fire before, they can see things coming a lot faster than guys that are just thrown out there or their first time out there,” he said. “Just seeing a couple things before they come at you.”

Holloman was thrown into action last week after both Justin Durant and Ernie Sims left the game against the Packers. And because both players had the headsets, it left Holloman having to get relayed signals from the coaches on the sideline.

“Hopefully we’ll have a guy with a microphone this time and we won’t have to do too many signals,” Holloman said. “Bruce will have the mic to start, and I’ll be the backup with it.”

Durant has been placed on IR with a hamstring injury and it’s unlikely Sims (hip/groin) will play. The Cowboys signed Orie Lemon to the roster and will get rookie Cameron Lawrence ready as well. Lawrence had to play most of the second half on the outside.

They certainly can’t afford any more injuries at linebacker. The team is preparing to play again without Sean Lee, who is dealing with a neck injury that likely keeps him out the rest of the regular season.

As for Carter, who missed one game already due to his hamstring, he knows both time and linebackers are running out.

“We understand we don’t have really any depth right now at linebacker, so if we can get guys back healthy like me, try to get Ernie there, he’s been banged up,” Carter said. “We just need to get anybody, really.”

And while Carter’s season hasn’t lived up to the high expectations set for him in the offseason, he knows he has a job to do, especially if he’s the only experienced starter out there, with Kyle Wilber on the strong side.

“My job is to try to lead the defense to a victory and just play as good as we can. When things get out of hand, try to get everybody to calm down and just try to get back to our game plan and play sound,” Carter said. “I’m up for the challenge. I know what’s ahead of me. We’ve just got to go out there and execute.”

And facing the Redskins won’t be easy, simply because of the way they run the football. Washington ranks third in the league at 140.9 rushing yards per game. Even with Kirk Cousins now in for Robert Griffin III, the Redskins will still rely on Alfred Morris, who ranks fifth in the league at 1,125 rushing yards.

IRVING, Texas – To the Cowboys, the term “cross-training” means learning multiple positions to be ready at a moment’s notice.

They’ve put that term to full use this year. Head coach Jason Garrett said it was essential particularly in training camp to cross-train the linebackers, and that could pay off now with all the mixing and matching to adjust for injuries.

“Sometimes you do it out of necessity in training camp to get through a practice or get through a preseason game,” Garrett said. “But you always want to cross-train your guys because it’s a long season. We understand that injuries happen.”

DeVonte Holloman’s getting set to start at middle linebacker for the first time in his career. Next to him on one side will be Bruce Carter, who many thought would shift to the middle after Sean Lee’s injury, considering he’s gotten experience there before.

Next to Holloman on the other side at strong side linebacker is Kyle Wilber, who began the year as a defensive end. Justin Durant, who played middle linebacker last week, had started the year as a strong side linebacker.

“Sometimes you can’t just simply put the next guy in,” Garrett said. “You have to find the next best guy from somewhere else. So we have done that in the past and it’s benefiting us now.”

That goes to show just how much versatility has been necessary for a defense searching for any possible answers at the tail end of the season.

Holloman said he’s been learning middle linebacker all season, but he never played the position before coming to the Cowboys. He was used to playing more of a hybrid safety/linebacker role in college.

“Coming from a safety to a hybrid guy and then finally playing linebacker, I’ve been learning since I got here, so it’s not much different,” Holloman said.

Holloman was forced into action last week after injuries to Durant and Ernie Sims. That was a tough circumstance for Holloman, but the brief experience he had earlier in the year helped out some.

“We all cross-train each others’ positions, so I was familiar with it, but I hadn’t done it,” Holloman said. “It was going out there and just learning on the fly.”

Garrett hopes Holloman can take what he learns from this experience moving forward.

“He’s a smart guy, he cares about football and he works very hard at it,” Garrett said. “Like some of the other young guys we’re talking about, he’ll learn from the experiences. When you get a chance to play Mike for the first time in the NFL, he’ll go back and reflect on those 60, 70 plays that he was in there and he’ll learn from them because he goes about it the right way. I think it was a good experience for him. He did a lot of good things, and hopefully he can build on that.”

Redskins coach Mike Shanahan said earlier this week he can’t worry about what personnel is on the field for the Cowboys, because in the NFL it’s such a common occurrence for one player to go down and another to have to step up and that everyone’s in the league for a reason.

With his band of backups, defensive coordinator Monte Kiffin said he still has confidence in his group with only two regular season games remaining to turn things around.  

“You go in your defensive room and split up and away you go,” Kiffin said. “You ain’t walking, get your heads up, let’s go. That’s the way it works. There ain’t no pouting around. We’ll be ready to play.”
