Cowboys rookie DE Marshawn Kneeland will undergo surgery for a meniscus tear in his right knee, potentially sidelining him for four to six weeks.

Why it matters: This injury adds to the list of defensive line setbacks for the Cowboys, who are already dealing with injuries to Micah Parsons and DeMarcus Lawrence.

What's new: An MRI revealed that Kneeland's ACL is intact, sparing him from a more severe injury.

Yes, but: While Kneeland's injury is not season-ending, his absence still poses a challenge for the Cowboys' defensive line rotation.

• The team has already been impacted by injuries during training camp and the regular season, including a season-ending torn ACL for Sam Williams.

What to watch: The Cowboys may consider reinforcing the defensive end position, potentially adding players to the practice squad to provide depth during Kneeland's absence.

What's next: Kneeland's surgery and rehabilitation will determine his recovery timeline, with a potential return in mid-November after a stint on injured reserve.

• Coach Mike McCarthy mentioned working with linebackers in Kneeland's position during the Steelers game as a contingency plan for further injuries.

The bottom line: The Cowboys will need to rely on their depth and adaptability on the defensive line as they navigate through a series of injuries.

• This presents an opportunity for players like Chauncey Golston, Tyrus Wheat, and Carl Lawson to step up and contribute.
