After Vandegrift High School won its state football championship last fall, an exhausted Carter Mannon fell asleep upon his arrival back home in Austin. The gold medal he earned that afternoon in Arlington was still draped around his neck.
This was Mannon’s finest hour. A year after he had considered quitting football, following a well-publicized 2023 incident regarding his peanut allergy and an alleged attack by former Lake Travis teammates, Mannon’s love for the game was restored. All it took was a change of scenery and a brand new team that believes in him.Â

Now a senior, the 6-foot-5, 270-pound offensive tackle is in his final season of high school football. Although there are no guarantees the Vipers will repeat as Class 6A Division II state champions, it’s likely Vandegrift will still be playing when the playoffs begin in November.

“It’s a completely different environment here at Vandegrift,” Mannon recently told the American-Statesman at his home in northwest Austin. “It’s truly a family. It’s a player-led program and that’s my favorite thing about it. We keep each other accountable. We’re really a close-knit team and that’s what makes us a good team. We’re connected.”

Vandegrift head coach Drew Sanders describes Mannon as a valued leader.
“Carter is a kid that every day he’s going to be talking to me about something,” Sanders said. “He is always so engaging and he seems to be enjoying where he is. I sense that he is happy to be a Viper football player. I can see how he’d sleep with his medal. I think he’s really proud to be a Viper and being a contributing team member.”
Mannon said he’s proud to be a state champion, but the “journey” to that 24-17 victory over Southlake Carroll last December at AT&T Stadium in Arlington made it more rewarding. The lineman was “in a dark place” when he decided to change his life.
Sanders told players what happened to Mannon at Lake Travis before the new kid walked into their Vipers field house for the first time. Most of them already knew his story.

A football journey that began with challenges
Mannon was a sophomore lineman for Lake Travis when an incident Oct. 6, 2023, inside the Cavaliers locker room shook him to his core. The team was slated to play Del Valle. He and a few of his teammates discussed dinner plans; one suggested they gather at Texas Roadhouse. Mannon balked, saying that restaurant is known for having peanut shells on the floor, and he’s allergic to peanuts.
Two of Mannon’s teammates asked whether peanuts could kill him.

“It absolutely could kill me,” he responded.

Unbeknownst to Mannon, two teammates put the allergen in his gear and shoes the day before. Mannon had peanut residue on his arm after reaching into his locker to grab his cleats and jersey. Within minutes, hives developed on his arms where the peanuts had touched him. One of the boys who Mannon said took part in the incident filmed and shared it. They were giggling, Mannon said.

Mannon said he went into “a state of shock” as soon as he realized his arms and the back of his hands were covered in hives. He was terrified.
“Even though it’s just a peanut, it could have killed me,” he said.
Mannon needed new equipment before he could safely take the field that night. The involved players — Gus Cordova, who had a Texas football scholarship pulled because of the incident and another teen, who has not been publicly identified — were suspended for two games before rejoining the team. The Lake Travis school district later said the incident did not fit the definition of bullying.
One year later, Mannon was a Vandegrift Viper.

Creating new friendships at a different school
Lake Travis is considered one of the elite high school football programs in Texas, claiming six state championships since 2007. The Cavaliers have produced some of the sport’s most recognizable stars, including Heisman Trophy winner and No. 1 overall NFL draft choice Baker Mayfield, now a quarterback with the Tampa Bay Buccaneers; former Ohio State All-American and current New York Jets wide receiver Garrett Wilson; and former Texas Longhorns and current Los Angeles Chargers place-kicker Cameron Dicker.
Through their attorneys, the Mannons filed a complaint in March 2024; the Lake Travis school district filed a standard motion to dismiss. They are awaiting the outcome, which could be a full dismissal, partial dismissal, or a denial of the motion to dismiss. There is “no timetable for the court’s decision,” said the family’s attorney, Chris Schulz.

The civil lawsuit, filed in the U.S. District Court of the Western District of Texas, seeks $1.5 million in damages. The lawsuit also asks that a judge compel the school district to implement training for staff and students about harassment based on disability, adopt policies for student complaints about disability-based discrimination, and modify programs to stop “engaging in unconstitutional and unlawful acts.”
There have been no incidents regarding Mannon’s peanut allergy at Vandegrift, Mannon said.

“The incident at Lake Travis will always linger,” said Mannon’s mother, Shawna Mannon. “It was life changing for Carter, for all of us. This affected our whole family, and we have all learned a tremendous amount from it. We are grateful for our new community. They have been the warmest embrace. I have established incredible, deep friendships in this short time we’ve been here. We are so proud to call the Vandegrift community home.”

Carter’s story worthy of a movie script
The story of Mannon’s peanut allergy reaction gained national traction in 2023 and has been included in a documentary created by the nonprofit Food Allergy Research & Education organization. According to FARE Chief Marketing and Communications Officer Jaime Rupert, the group focuses on three strategic pillars: research, education and advocacy.
FARE produced a 25-minute documentary called “A World Unaware: When Every Bite Matters.” It is slated for release in November.

Carter and Shawna Mannon are featured prominently in the film, which explores the experiences of more than 33 million people in the U.S. who live with food allergies, a life-threatening condition that FARE says claims 150 to 200 lives a year and leads to about 30,000 emergency room visits a year. Roughly 1 in 11 adults and 1 in 13 children have food allergies.
When Rupert learned about Mannon’s high school experiences, FARE wanted him to be part of the documentary.
In the film, Mannon describes the first time he experienced a food allergy. At 9 months, he dipped his hand in a bottle of peanut butter and rubbed it on his face. He soon developed hives.
“Carter’s story is important to the entire food allergy community and to those who don’t understand the disease,” Rupert said. “The idea that weaponizing a food allergen is quite concerning. The perspective/idea of was this attempted murder or not even bullying is a catalytic moment for all of us. What is bullying if this isn’t?”

Rupert and her FARE colleague, Jennifer Webb, recently flew to Austin to attend a Vandegrift game. They spent most of their time with Carter and Shawna Mannon. A screening of the documentary will be shown in Austin in November.
This is how Rupert described Carter: “Impressive. Brave. Humble. Dignified. The wisdom he has gained from his experience is palpable. He is kind and smart. He speaks from his heart and is thoughtful. He is someone I admire very much; he loves football.”
Shawna Mannon said her son has weathered a storm the past two years and is eager for what’s next.
“He’s excited to be partnering with FARE to continue educating communities on the dangers and seriousness of living with food allergies,” she said. “He is also big on educating on the importance of having epinephrine (a life-saving treatment used for severe allergic reactions) accessible in as many places as possible. That includes schools, airplanes, restaurants, arenas. Every first-aid kit should have epinephrine.”

Carter Mannon said he wants to be an advocate for people with food allergies. Last year he flew to Kansas City, Mo., to help present the FARE Champion Award to Brittany Mahomes, wife of Kansas City Chiefs quarterback Patrick Mahomes, for their dedication to the food allergy cause. The Mahomes have two children with severe food allergies.
Carter Mannon said it was “an honor” to be part of the Mahomes gala, and said he enjoyed meeting the three-time Super Bowl MVP. Patrick Mahomes later mailed him an autographed football.

That’s just a snippet of what might lie ahead for Mannon, who aspires to play college football next season and continue to be a spokesperson for people with food allergies for years to come. Instead of being remembered as a victim of a potentially disastrous food allergy “prank” two years ago, he wants to serve others who live with allergies.
“I’m more than happy to do anything I can with FARE,” he said. “I’ll always be an advocate. If there’s an opportunity for me to speak up on it, I’ll take it. It surprises me to know how many people don’t understand it’s as serious as it is. It’s not something you have a choice on.”
