Dallas Cowboys rookie defensive end Marshawn Kneeland will undergo surgery for a meniscus tear in his right knee, sidelining him for four to six weeks. Fortunately, his anterior cruciate ligament is intact, avoiding a season-ending injury.

This situation compounds the Cowboys' defensive line woes, as Micah Parsons is also dealing with an ankle sprain and DeMarcus Lawrence is on injured reserve with a foot injury. Both are expected to return in mid-November.
