Commanders HC Dan Quinn said RG Sam Cosmi is in concussion protocol.

21 September 2026

Cosmi will need to clear concussion protocol in time to play in Week 3’s home opener against the Seahawks. Cosmi took a hard helmet-to-helmet shot from teammate Kaytron Allen while trying to make a block and immediately went down on the field for several minutes. Rookie sixth-rounder Matt Gulbin took over in his absence and could be in line to draw the start for him next week if Cosmi is unable to play. Quinn also said DT Javon Kinlaw suffered a shoulder injury and LT Brandon Coleman suffered a finger injury in the loss.
