Some notes

For the Chiefs, two players did not participate in Thursday’s practice: left tackle Josh Simmons (Back) and safety Chamarri Conner (Knee). Both have missed nearly a month of practice.
No Kansas City players were listed as limited participants on Thursday.
Defensive end Ashton Gillotte (Foot) was listed as a full participant after missing weeks of practice due to rupturing his plantar fascia. Rookie edge rusher R Mason Thomas (Hamstring) also practiced in full after the injury popped up last week.
Quarterback Patrick Mahomes is cleared to start in Week 1, according to head coach Andy Reid. He sounds ready to roll.
