What happened: Patrick Mahomes entered camp fully cleared for practice after surgery to repair torn ligaments in his left knee. His preseason participation remains a decision for the Kansas City Chiefs' coaches and medical staff.

Why it matters: A strong opening stretch would reduce pressure to make every result hinge on peak quarterback play. It also would preserve room for improvement as the 2026 season advances.

What to watch: Watch whether Mahomes takes preseason snaps and whether his workload changes as camp progresses.
