McLaurin has been placed in the league's concussion protocol, Kareem Copeland of The Washington Post reports.
McLaurin didn't practice Tuesday, and the reason for his absence wasn't known at the time. It's not clear what type of symptoms McLaurin is dealing with, but he'll need to clear the protocol in order to play Week 17, and Washington figures to proceed with caution given that the team has nothing to play for but draft position.
