McKissic has a concussion and he didn’t participate in practice on Wednesday or Thursday. Another day on the sideline Friday will likely signal his absence from the lineup when the team takes the field against the Raiders on Sunday.
Landon Collins has also missed practice both days this week. Collins, who is playing more linebacker than safety this season, has a foot injury.
Washington announced that cornerback Benjamin St-Juste has been placed on injured reserve. He’s been out with a concussion. Cornerback Darryl Roberts was activated from injured reserve in a corresponding move.
