Layton Vander Asch, Blake Jarvin ruled among injured Dallas Cowboys

Cowboys linebacker Leighton Vander was one of a trio of Dallas players to be ruled out of Sunday’s game against the Rams in Los Angeles due to an Ash injury.

Vander Ash was spared a collar bone injury in the first half.

Tight end start Blake Jarvin and backup offensive tackle Cameron Irving were ruled out for the second half with a knee injury.

The Cowboys’ defense was on the field for 23 plays in the first quarter, allowing open-drive touchdowns. The second drive ended with a missed field goal attempt. Vander Ash was not credited with the tackle.

Vander Ash is playing in his first game since last week’s 10th due to a neck injury. Television replays showed the Cowboys’ medical staff testing Vander Ash’s neck. He had neck surgery, but said he felt fine during training camp.

Vander Ash took over as middle linebacker this season, positioning alongside Jaylon Smith, and serving as a defensive signal-caller.

With Sean Lee on injured reserve and not missing the first three matches due to a pelvic issue, the Cowboys have veteran Joe Thomas and Justin March, who are mostly a special-teasers at reserve. Luke Gifford is in the midst of the team’s inaction and was dealing with a hamstring issue.

Jarvin ran to his right knee after falling to the ground running a route in the opening half. It came just one or two plays after catching a 12-yard pass. The Cowboys signed Jordan to a four-year, $ 22 million contract in the offshin to replace Jason Witten, who missed just one game in his 16 seasons in Dallas.

Irving swung his knee, stopping special teams.
