The Washington Commanders lost a second defensive line starter for the season in less than a week as Javon Kinlaw underwent season-ending knee surgery, a source told ESPN's Adam Schefter.
Kinlaw, who played end in their base defense and tackle in their nickel package, injured his MCL in a Week 6 loss at San Francisco.
Two days before the Week 8 win over Philadelphia, Daron Payne fractured his foot in what was described as a "fluke injury" during a light Friday practice. He, too, is out for the season. Like Kinlaw, Payne started at end in their 3-4 base front and played tackle in their nickel package.
