Cosmi (concussion) has been ruled out ahead of Sunday's game against the Seahawks.
Cosmi entered the league's five-step protocol after suffering a concussion during the Commanders' Week 2 loss to the Cowboys. The right guard was unable to be cleared by an independent neurologist, meaning he will be sidelined for Sunday's game. Andrew Wylie or Tanoa Togiai will likely start at right guard in Cosmi's absence.
