Lions quarterback Jared Goff was rocked by a Commanders defender Saturday night after throwing a pivotal pick-six in the first half.
Goff was intercepted by Quan Martin before the defensive back returned the interception 40 yards for a touchdown, and the quarterback was crushed in the upper chest by Washington's Frankie Luvu while attempting to chase down the play.
The hit sent Goff flying backwards to the ground and left him out on the next drive as backup Teddy Bridgewater was forced to take over with Detroit trailing 24-14.
Goff was then seen being treated in a medical tent on the sideline before walking to the locker room.
The Lions cut into Washington's lead in Goff's absence when Jameson Williams took one end for a 61-yard score, before Jayden Daniels responded with a five-yard touchdown to Zach Ertz.
Goff then emerged on the final drive of the half and threw another interception into the end zone.
It was a difficult first half for Goff, as he committed three turnovers, the first of which was a fumble in the first quarter.
