What happened: Andy Reid said Patrick Mahomes will start barring a surprise setback this week. The Sept. 14 game kicks off at 8:15 p.m. ET at Arrowhead Stadium.
Why it matters: Mahomes had secured full practice clearance before camp and handled essentially all first-team reps. Kansas City then hosts Indianapolis on Sunday night in Week 2, extending its prime-time opening stretch.
What to watch: Kansas City's final injury report is the next checkpoint before Monday's kickoff.
