Washington Redskins defensive end Jonathan Allen will have an MRI on Monday to determine the severity of a sprained MCL, according to multiple reports.
The 2017 first-round draft pick injured his left knee in the season-opening loss to the Philadelphia Eagles and is considered week-to-week.
He left the game after playing seven snaps in the first quarter and did not return, replaced in the lineup by second-year defensive lineman Tim Settle.
Allen, 24, started all 16 games for the Redskins in 2018 and registered 61 tackles, 15 quarterback hits and eight sacks.
