Olathe Public Schools pushed varsity football kickoffs to 8 p.m. the week of Sept. 1. The district also barred other high school competitions from starting before 6:30 p.m. as heat indexes topped 115 degrees across the Kansas City metro, KCUR reported.

Olathe East Athletics announced on X that the Hawks' football game against Shawnee Mission North on Sept. 3, moved to an 8 p.m. start because of the heat. The district shifted high school and middle school practices to before school, later in the evening or indoors. Some sub-varsity and middle school competitions were rescheduled or shortened.

Meteorologists say the metro has not dealt with a heat wave this long in 14 years.

The schedule changes come days after William Jewell College running back MicahJo Barnett, 20, collapsed on the sideline during the season opener against Fort Lewis College on Aug. 29. Barnett, a Shawnee Mission native and former Liberty North High School standout, had just scored a touchdown in the first quarter.

He told a sideline doctor he was having trouble breathing before losing consciousness, KCUR reported. Paramedics stationed at the game began treatment, but Barnett died at Liberty Hospital.

His cause of death has not been released.

The Clay County medical examiner's autopsy results are pending. It was 97 degrees in Liberty at 1 p.m. on Aug. 29, according to the National Weather Service, but whether heat played a role is unknown.

Barnett is the sixth high school or college football player to die in the KC region during summer months in the past eight years, the Kansas City Star reported. The five previous deaths were all found to be heat-related, including Myzelle Law, 19, at MidAmerica Nazarene University in Olathe in July 2023 and Ovet Gomez Regalado, 15, at Shawnee Mission Northwest in August 2024.

How Olathe monitors heat

A district spokesperson told KCUR that Olathe follows Kansas State High School Activities Association (KSHSAA) guidelines for all outdoor extracurricular activities. Athletic trainers from the University of Kansas Medical Center measure the wet bulb globe temperature, or WBGT, each day at the activity site. WBGT accounts for air temperature, humidity, wind speed, sun angle and cloud cover.

The KSHSAA policy, updated in April 2026, sets five zones:

• Below 80 degrees WBGT: Normal activities with rest breaks every hour.
• 80–84.6 degrees: Longer rest breaks. A cold-water immersion tub must be prepared.
• 84.7–87.7 degrees: Two-hour maximum. Football players limited to helmets and shoulder pads.
• 87.8–89.7 degrees: Activities should be delayed or rescheduled. No football pads. No conditioning.
• 89.8 degrees or above: No outdoor activity.

Readings must be taken 30 to 60 minutes before activity begins whenever air temperature hits 80 degrees. All participants must have unrestricted access to water regardless of the zone.

Kansas vs. Missouri

The National Federation of State High School Associations (NFHS) and its Sports Medicine Advisory Committee called in August 2026 for a "paradigm shift" in how coaches condition linemen, who account for 97% of exertional heat stroke deaths in football, the Johnson County Post reported. The recommendations include banning post-practice sprinting for linemen and prohibiting exertion drills as punishment.

Neither Kansas nor Missouri requires coaches to follow those guidelines. Jeremy Holaday, KSHSAA assistant executive director, told KCUR in an August email that the NFHS recommendations are ones "we have been operating under for two seasons now."

Missouri's WBGT thresholds are also higher. MSHSAA does not ban all outdoor activity until 92 degrees WBGT, compared with KSHSAA's 89.8-degree cutoff. MSHSAA spokesman Andrew Kaufman told KCUR in August that the association does not mandate specific heat-related protocols because it cannot directly supervise every practice and contest statewide.

Hundreds of teammates, students and community members gathered for a candlelight vigil on the William Jewell quad the night of Aug. 29. The college said any internal investigation would wait until the medical examiner finishes its work.
