Mark Herzlich of Boston College Eagles Diagnosed with Cancer: A Story of Resilience and Hope

In May 2009, as the Boston College Eagles prepared for a promising season, their star linebacker, Mark Herzlich, received shocking news that would alter his path—and inspire countless others. At the height of his collegiate career, Herzlich was diagnosed with Ewing’s sarcoma, a rare and aggressive form of bone cancer. This diagnosis not only interrupted his life as a standout athlete but also set the stage for one of the most remarkable comebacks in college sports history.

Early Triumphs on the Gridiron

Herzlich burst onto the scene at Boston College in 2006. By his junior year, he had achieved staggering success: named ACC Defensive Player of the Year in 2008, earning First-Team All-American honors, and leading the team with 110 tackles, six interceptions, and a defensive touchdown (bceagles.com, bcinterruption.com). His dominance made him a projected top-15 selection in the 2009 NFL Draft (en.wikipedia.org). Touted as one of the best linebackers in the nation, Herzlich embodied the dreams of an Eagles alum destined for stardom .

Devastating Diagnosis: Ewing’s Sarcoma

Everything changed in the summer of 2009. On May 14, 2009, Herzlich announced he had been diagnosed with Ewing’s sarcoma, a rare and often aggressive cancer affecting bone and soft tissue (en.wikipedia.org). Initial symptoms—pain and tenderness in his left femur—led to medical testing that confirmed the diagnosis (cbsnews.com). Despite a stellar football career, Herzlich faced a battle that went far beyond the gridiron.

A Grueling Treatment Journey

Herzlich embarked on an intense treatment regimen that included 50 rounds of radiation, six months of chemotherapy, and the surgical implantation of a titanium rod in his femur (tcjayfund.org). Reflecting on his diagnosis, he shared that discovering cancer “felt like forever ago” and that he viewed it as a “stepping stone” to overcome (espn.com).

During treatment, an outpouring of support came from coach Coughlin’s Jay Fund community, classmates, and fans, offering prayers and encouragement (tcjayfund.org). Herzlich’s best friend even sacrificed a summer vacation to stand by his side throughout the treatments (en.wikipedia.org). That level of camaraderie was a vital lifeline during one of the most challenging periods of his life.

Declared Cancer-Free and Triumphant Return

Miracles do happen. On October 3, 2009, during ESPN College GameDay broadcast live from Boston College, Herzlich announced he was 99 percent cancer-free (en.wikipedia.org). With the public watching, he shared the news that he could beat cancer and return to the field.

True to his word, Herzlich made an unforgettable comeback in the 2010 season opener against Weber State, registering five tackles (en.wikipedia.org). He played all 13 games, earned the Rudy Award, ACC Brian Piccolo Award, and was the third leading tackler with 65 total stops (bceagles.com). His comeback was hailed as one of the greatest in college athletics.

Legacy and Continued Influence

Despite his stellar return, Herzlich went undrafted in the 2011 NFL Draft—primarily due to medical concerns (letsengage.com). However, the New York Giants signed him as a free agent later that year. His relentless spirit secured him a place on the team that would go on to win Super Bowl XLVI in 2012 .

Herzlich's story earned him the Best Comeback Athlete ESPY in 2011 (en.wikipedia.org). He also received several honors for courage, including the Disney Spirit Award, Nils V. "Swede" Nelson Award, honorary Lott Trophy, and ACC Commissioner's Cup (bceagles.com).

Giving Back: Advocacy and Professional Life

Since retiring from football in 2018, Herzlich has continued to inspire others. He authored a memoir, What It Takes: Fighting For My Life and My Love of the Game, and became a motivational speaker, podcast host, and ACC Network analyst (letsengage.com). He is also active in charitable work, partnering with organizations like the Joyful Heart Foundation and International Justice Mission (people.com).

Reflecting on Courage, Resilience, and Legacy

Mark Herzlich’s journey transcends football. His battle with Ewing's sarcoma at age 21, triumphant return, and unwavering resolve continue to resonate with fans, athletes, and individuals fighting adversity. From the Carson tunnels of Boston College to the Super Bowl stage, his story is one of courage, faith, and relentless determination.

Today, Herzlich’s experience serves as a beacon of hope for cancer warriors worldwide. It underscores the power of community support, mental grit, and the belief that with enough resilience, even the most daunting challenges can be overcome.

His tale reminds us that the greatest victories may not be measured in touchdowns or tackles—but in the human spirit’s capacity to rise, endure, and inspire.
