Patrick Mahomes Set to Start for Chiefs in Week 1

Patrick Mahomes will start at quarterback for the Kansas City Chiefs in their Week 1 opener against the Denver Broncos. The two-time MVP has completed a remarkable recovery from December surgery to repair torn ligaments in his left knee, a process doctors initially thought could keep him out until October. His return is official for the Monday Night Football clash at Arrowhead Stadium on September 14, 2026.

How Did Mahomes Beat His Recovery Timeline?

Mahomes’s accelerated return is the story of an offseason. He suffered tears to his ACL and LCL against the Los Angeles Chargers in December 2025. Medical personnel gave a cautious timeline that pointed toward an October 2026 return. But Mahomes surged past every benchmark in his rehab. He worked with the first team throughout training camp and made his goal of being ready for Week 1 a reality. He did not take a single preseason snap, a plan the Chiefs stuck to deliberately. Wide receiver Xavier Worthy returned early to Kansas City to work on timing with Mahomes, who spent his rehab days watching World Cup matches.

Who Will Protect Mahomes’s Blind Side?

A major subplot to Mahomes’s return is the reshuffled offensive line protecting him. Starting left tackle Josh Simmons, the team’s 2025 first-round pick, is unlikely to play in Week 1 due to a lingering back injury. Head coach Andy Reid confirmed the situation on Tuesday, September 8. That means undrafted rookie Kahlil Benson is likely to start at left tackle, tasked with guarding Mahomes’s blind side against a tough Denver pass rush. Benson, out of Indiana, earned a roster spot after a tryout in May. He played right tackle in college and has no recorded snaps at left tackle from his time at Indiana, according to Pro Football Focus. Only two undrafted rookies have started Week 1 at offensive tackle since 2018, making Benson’s potential debut a rare feat.

What Does His Return Mean for the Chiefs’ Season?

Mahomes’s availability is a massive boost for a Chiefs team that finished 6-11 and missed the playoffs entirely last season. His presence immediately raise Kansas City back into the AFC West conversation. The team upgraded at running back by signing former Super Bowl MVP Kenneth Walker III. But questions remain about the wide receiver group, which will rely on Rashee Rice, Xavier Worthy, and others to step up. The entire offensive operation, including star tight end Travis Kelce, runs through Mahomes.

Are There Any Concerns About Week 1 Rust?

With no preseason game action, some wonder if Mahomes will show rust. The only other time he went a full preseason without playing was in 2020 when exhibition games were canceled. Coach Reid has emphasized practice reps, including one-on-one sessions, to sharpen timing. Worthy expressed confidence the connection would be ready. The true test comes on September 14 against a division rival.

• Mahomes is confirmed to start against the Denver Broncos on Monday Night Football, September 14.
• His recovery from December knee surgery beat initial medical projections by over a month.
• Undrafted rookie Kahlil Benson is the likely starter at left tackle due to Josh Simmons’s back injury.
