What happened: Tyler Smith returned to practice for Dallas as the Cowboys worked through a key availability update on offense. Malik Hooker also underwent surgery, leaving the defense with an immediate question over who will handle the green-dot communication role on the field.

Why it matters: Smith's return matters for an offensive front trying to regain stability early in the regular season. Hooker's status matters just as much on the other side, because the green-dot job controls defensive communication, checks and alignment before the snap.

What to watch: Dallas' next practice and injury updates should offer the clearest read on Smith's workload and Hooker's short-term availability. The next clue on defense is whether the Cowboys settle on a primary communicator or keep that role fluid.
