ESPN's in-game injury board lists Arroyo as doubtful with a shoulder issue during Thursday Night Football. That matches the club's sideline update. RotoBaller also carried the doubtful designation shortly after it posted.
What is confirmed is the in-game status: Arroyo left the contest and the Seahawks called him doubtful to come back. What is not confirmed is how serious the shoulder is beyond tonight, or whether he will need further tests after the final whistle.
At halftime, fantasy analyst Nathan Jahnke had Arroyo on five of Seattle's 30 offensive snaps, with A.J. Barner on 29 and Nick Kallerup and Eric Saubert also mixed in. Barner was already the primary tight end in the game script before the injury update, so the immediate snap shift is toward him and the remaining tight ends rather than a sudden scheme change.
Arroyo is a young piece of Seattle's tight end room, not the every-down option. A shoulder issue that ends his night still matters for dynasty and deeper contract formats that roster him as a stash or TE2. It does not rewrite the Seahawks' passing hierarchy on its own while Barner is healthy and active.
Denver led 14-3 when the update landed, and the game was still in progress in the third quarter with about 7:46 remaining on the ESPN clock when this desk last checked the board. In-game designations can move again if he warms up or if the club later rules him out for the rest of the night.
