Mahomes Most Likely to Start Week 1 for Chiefs

Rehab has met key medical and on-field milestones, leaving the team to make a day-to-day clearance decision before Monday night.

Overview

  • Chiefs coach Andy Reid said Tuesday that Patrick Mahomes is “most likely” to start the Monday Night opener against the Denver Broncos unless there is a late setback.
  • Mahomes tore the ACL and LCL in his left knee in mid-December 2025, had surgery the next day and completed an accelerated rehab program that included being cleared for full practice before training camp.
  • Kansas City held Mahomes out of all preseason games, monitored his workload in camp with a protective brace, and gave live reps to backups while protecting his knee.
  • Left tackle Josh Simmons is a long shot to play because of a back issue, so undrafted rookie Khalil Benson is expected to start at left tackle and protect Mahomes' blind side.
  • Denver is preparing as if Mahomes will be healthy and mobile, and his likely return improves the Chiefs’ outlook but raises short-term questions about pass protection and early-season load management.
