Hill suffered a concussion during Sunday's contest at Washington, Katherine Terrell of The Athletic reports.
Hill remained on the turf after taking a hit to the helmet on an attempted catch in the second quarter and needed a cart to get to the locker room. Now that he has a confirmed concussion, he'll be subject to the NFL's protocol for head injuries in order to be cleared to resume game action. While Hill navigates his way through each of the five steps, Trevor Siemian and Ian Book are the remaining quarterbacks on the Saints behind starter Jameis Winston.
