The Commanders activated Mathis (calf) from the injured reserve list Saturday, Adam Schefter of ESPN reports.
Mathis was placed on IR at the end of training camp after he sustained a calf injury in a preseason game. He played in the 2022 season opener but sustained a season-ending injury when he tore his meniscus. Now that he's healthy, the 2022 second-round pick out of Alabama will provide depth at defensive tackle behind the talented duo of Daron Payne and Jonathan Allen.
