In the high-stakes world of the NFL, a missed kick usually means public scorn, social media memes, and a long week of film study. For Korean-American kicker Younghoe Koo, one particular whiff last December didn’t just cost his team a few points—it inadvertently saved a stranger’s life.

The story sounds like a Hollywood script: A 32-year-old placekicker’s botched field goal attempt makes a Kentucky man laugh so hard he suffers a seizure, leading doctors to discover a tennis ball-sized brain tumor that could have killed him. Yet this isn’t fiction. It’s the improbable true story that has connected Koo, now with the Atlanta Falcons, and Mark Tuseyker, a 41-year-old Lexington resident, in what medical professionals are calling a “medical miracle.”

The Kick That Changed Everything

The moment occurred during a December 15, 2025 game between Koo’s then-team, the New York Giants, and the New England Patriots. With 8:42 remaining in the second quarter and the Giants trailing 10-3, Koo trotted onto the field for what appeared to be a routine 47-yard field goal attempt.

What happened next defied all expectations. As Koo approached the ball, his plant foot slipped on the frozen MetLife Stadium turf. Instead of striking the ball cleanly, his right foot dug into the ground just inches before contact. The ball never left the tee. The Patriots took over on downs, and the Giants would proceed on to lose 33-15, their fourth straight defeat.

“I’ve never seen anything like it in my 15 years covering the NFL,” said ESPN analyst Louis Riddick, who called the game. “Koo is one of the most reliable kickers in the league. That miss wasn’t just unusual—it was physically impossible under normal circumstances.”

For most NFL players, such a high-profile mistake would mean days of online ridicule. For Koo, who had already established himself as one of the league’s most accurate kickers (90.3% on field goals in 2024), the miss was particularly painful. What neither he nor his teammates knew at the time was that 600 miles away in Lexington, Kentucky, that same moment was about to develop into a lifeline.

The Laugh That Saved a Life

Mark Tuseyker was watching the game from his living room recliner, his wife Mallory curled up beside him on the couch. The couple had made a tradition of watching Sunday Night Football together, a weekly ritual that had survived Tuseyker’s recent health scares.

“I’ve seen some bad kicks in my life, but this one was different,” Tuseyker told reporters during a press conference at UK HealthCare on Monday. “There was something about the way Koo just stood there, staring at his foot like he couldn’t believe what had happened. I lost it. I mean, I was laughing so hard I was crying.”

What started as amusement quickly turned alarming. Tuseyker’s laughter escalated into uncontrollable convulsions. His wife, a veteran nurse at the UK HealthCare Neuroscience Institute, immediately recognized the symptoms of a grand mal seizure.

“I’ve worked in neuro rehab for 12 years,” Mallory Tuseyker said. “But nothing prepares you for seeing your own husband go through that. One minute he’s laughing at an NFL kicker’s blooper, the next he’s convulsing on our living room floor.”

An ambulance rushed Tuseyker to the emergency room, where a CT scan revealed the shocking truth: a 6.2-centimeter tumor in his left frontal lobe. Neurosurgeons at UK HealthCare later confirmed it was a meningioma—a typically benign but potentially deadly brain tumor that had been growing undetected for years.

A Tumor’s Silent Growth

Dr. Elizabeth Chen, the lead neurosurgeon on Tuseyker’s case, explained that the tumor had likely been present for 3-5 years before its discovery. “Meningiomas are slow-growing, which is why many patients don’t experience symptoms until the tumor reaches a critical size,” she said. “In Mr. Tuseyker’s case, the seizure was the first—and fortunately, last—warning sign.”

The surgery, performed on January 10, 2026, lasted 7 hours and 43 minutes. Dr. Chen and her team successfully removed 98% of the tumor, with the remaining 2% deemed too risky to extract due to its proximity to critical brain structures. Tuseyker spent three weeks in the hospital before beginning outpatient rehabilitation.

“I owe my life to that kick,” Tuseyker said, his voice cracking during Monday’s press conference. “If I hadn’t been watching that game, if I hadn’t laughed that hard, if my wife hadn’t been a nurse… I might not be here today.”

The Kicker’s Perspective

Younghoe Koo, who has remained largely silent about the incident since joining the Falcons in March, finally addressed the story during a media availability session on Tuesday.

“When I first heard about this, I couldn’t believe it,” Koo said through an interpreter. “As kickers, we’re trained to block out the noise after a miss. But knowing that something so negative for me turned into something so positive for someone else… It changes how I think about those moments.”

Koo’s agent, David Dunn, confirmed that the kicker has been in contact with Tuseyker’s family and plans to visit Lexington later this summer. “Younghoe wants to meet Mark in person,” Dunn said. “This isn’t about publicity for him. It’s about closure—for both of them.”

The Science Behind the Seizure

Neurologists have weighed in on the unusual chain of events that led to Tuseyker’s diagnosis. Dr. Sidney Kramer, a seizure specialist at Massachusetts General Hospital, explained that laughter-induced seizures are rare but not unheard of.

“Laughter is a complex neurological process that involves multiple brain regions,” Dr. Kramer said. “In Mr. Tuseyker’s case, the tumor was located in the frontal lobe, which controls emotional expression and motor function. The combination of extreme laughter, which increases intracranial pressure, and the tumor’s location likely triggered the seizure.”

Dr. Kramer emphasized that while the story is extraordinary, it highlights the importance of paying attention to unusual symptoms. “Seizures can manifest in many ways—confusion, muscle twitches, even unexplained emotions. Mr. Tuseyker’s case is a reminder that our brains often send warning signs long before a crisis occurs.”

From Viral Infamy to Medical Advocacy

The story of Koo’s miss and Tuseyker’s tumor has gone viral, with the hashtag #KooSavedMe trending on social media. The attention has sparked a broader conversation about brain health awareness, particularly among middle-aged men who are statistically less likely to seek regular medical checkups.

The National Brain Tumor Society has already reached out to both Koo and Tuseyker about potential public service campaigns. “This story has captured the public’s imagination in a way that traditional awareness campaigns often don’t,” said NBTS CEO David Arons. “We’re exploring ways to leverage this moment to encourage early detection and regular screenings.”

For his part, Tuseyker has embraced his new role as an advocate. “If my story can convince even one person to get a checkup they’ve been putting off, then something great has arrive from all of this,” he said. “And hey, if that checkup happens due to the fact that someone remembers a funny NFL blooper, even better.”

What’s Next for Koo and Tuseyker

Koo, who signed a three-year, $12 million contract with the Falcons in March, is preparing for the 2026 season. Despite the offseason drama, his focus remains on improving his craft. “I’ve reviewed that kick a hundred times,” he said. “The conditions were bad, but that’s no excuse. I need to be better.”

The Falcons, who finished 7-10 in 2025, are counting on Koo to stabilize their special teams unit. Head coach Raheem Morris has already praised Koo’s professionalism. “Younghoe’s been through a lot this offseason, but he’s handled it with class,” Morris said. “We’re lucky to have him.”

As for Tuseyker, he continues his recovery with weekly physical therapy sessions. His doctors expect a full recovery, though he’ll need regular MRIs to monitor for any tumor regrowth. “I’m just grateful to be here,” he said. “And I’ll never complain about a bad kick again.”
