Steelers WR JuJu Smith-Schuster left practice early Thursday with a knee injury.
Not the best of signs as this was a downgrade for JuJu after he practiced in full Wednesday. We’ll see if he suffered some sort of setback. Friday will be very telling for his potential to play in a key game Sunday night against the Bills. James Conner was a full participant, so it wasn’t all bad for Pittsburgh. If JuJu can’t go, Diontae Johnson will have another chance to shine after his breakout performance in Week 14.
