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.
By the numbers: The gap from Mahomes' Dec. 14 injury to Kansas City's Sept. 14 opener is 274 days.
What to watch: Watch whether Mahomes takes preseason snaps and whether his workload changes as camp progresses.
