What happened: Buffalo Bills wide receiver D.J. Moore did not participate in Friday's practice due to a shoulder injury. He emerged about halfway through the media viewing portion to observe the session.

Why it matters: His absence creates uncertainty around his status for this weekend's contest. Moore, who scored his first touchdown for the Bills in September, remains a central piece of the passing attack.

What to watch: Buffalo's upcoming injury designations will clarify his availability for the next game.
