Thornton is being evaluated for a possible concussion and is questionable to return to Sunday's game against the Chargers.
Thornton took a helmet-to-helmet hit from Tony Jefferson early in the fourth quarter, which resulted in the latter being ejected from Sunday's game. With Hollywood Brown (personal) inactive, JuJu Smith-Schuster, Nikko Remigio and Jalen Royals are all candidates to see more snaps on offense for as long as Thornton is out of the game.
