Ioannadis suffered the injury in the second quarter of Sunday’s loss to the Cleveland Browns. Rookie defensive end Chase Young also exited the game in the second quarter with a groin injury.
On a talented defensive line that features five first-round picks, Ioannadis, a fifth-round pick in 2016, has stood out as Washington’s best interior pass rusher. Last season he led the team with 8.5 sacks.
This season, Ioannadis was in the first of a three-year, $21.75 million extension he signed last year. He had 1.5 of Washington’s NFC-leading 13 sacks before his injury.
