What happened: Locke exited against the Washington Commanders and was taken directly to the medical tent. The defensive back was helped to the sideline without walking under his own power.

Why it matters: The injury challenges a Dallas safety rotation that is already without Malik Hooker. The secondary, which added Caleb Downs in the draft, must manage the depth concerns while protecting a 17-3 advantage.

What to watch: Medical staff will evaluate the safety to determine his status for the remainder of the ongoing contest.
