In short
Sebastian Joseph-Day is in the rotation at nose tackle for PIT — 36% of the snaps in his best week of 5. He has a triceps injury. In week 7 he did not practise. His team has not listed him on the final report. We called him PLAY in week 7 and he did not play.
The reader concurs · grade A
The team itself announced on 22 October that Joseph-Day was placed on the Reserve/Injured List (P4), with the Steelers' own tweet confirming it (P1). IR carries a mandatory absence — 'out for at least the next four weeks' with earliest return in Week 11 versus Philadelphia (P1), and 'By rule, he will miss the team's next four games' (P2) — so he cannot be active on 25 October. The Wednesday DNP with a triceps injury (P5) is the precursor to that move, not a competing signal.
