Amanda Mack, a 20-year-old Holy Cross junior who documented her fight against a rare blood disorder on social media, died just three months after her diagnosis, leaving behind a volleyball career cut short and a family in mourning.
Mack died Wednesday night, September 16, her family announced. The Holy Cross women's volleyball team published a tribute on its Facebook page confirming the loss. KTRE reported that Mack had been diagnosed with severe aplastic anemia, a rare condition in which the bone marrow fails to produce enough blood cells, roughly three months before her death.
She was a Florida native who had transferred twice to keep playing the sport she loved, moving from the University of Cincinnati to Eastern Kentucky University, where she played one season as a sophomore with the Colonels, and then to Holy Cross for her junior year.
In July, Mack woke up feeling unwell. She passed out and was rushed to the hospital. Her hemoglobin had dropped to 4, and her platelet count had fallen to 1, numbers so low she was listed in critical condition. Her body, she later explained, had depleted its own blood supply and lost the ability to clot. Doctors loaded her with blood and platelet transfusions to stabilize her.
Mack shared the details herself on Instagram, writing candidly about her emergency and the confusion that followed. Doctors initially suspected leukemia. After two bone marrow biopsies, they reached a different conclusion: severe aplastic anemia, a disorder in which the immune system attacks the bone marrow and shuts down blood cell production.
In her own words, posted to Instagram in July:
"I ended up passing out and went to the hospital. My hemoglobin was at 4 and my platelets were at 1. I was in critical condition. Somehow my body had depleted my blood supply and ability to clot. I was admitted to the hospital and loaded full of blood and platelet transfusions."
The post was accompanied by a photo of Mack, a young woman who just weeks earlier had been preparing for another collegiate volleyball season. The contrast between her athletic life and her hospital bed told the story more plainly than any medical briefing could.
Tragedies among young athletes have become an all-too-familiar pattern in recent years. A William Jewell football player also died at 20 during a game in Missouri, a reminder that youth and fitness offer no guarantee against sudden medical catastrophe.
On August 14, Mack posted an update that carried a tone of cautious optimism. She had completed immunosuppressive therapy, a treatment designed to stop her immune system from destroying her bone marrow, and reported minimal adverse reactions.
She wrote on Instagram:
"Now we wait for my body to fix my immune system and reproduced my bone marrow. I should be able to go home by the end of next week and get to start Physical Therapy and the rest of my healing journey!"
That post, dated just over a month before her death, was the last public update from Mack that has been reported. The New York Post reported that Mack had also undergone two emergency surgeries and was set to receive a bone marrow transplant at Tampa General Hospital. She never made it to that transplant.
The gap between her hopeful August 14 message and her death on September 16, barely five weeks, underscores how quickly severe aplastic anemia can overwhelm even a young, otherwise healthy body. Mack went from talking about physical therapy and going home to gone.
Mack's death drew tributes beyond her college teams. D1 Training Hardin Valley, a fitness facility, posted on Instagram that its "D1 family is heartbroken by the loss of Amanda Mack," adding that she "approached every session with a phenomenal attitude and left a lasting impact on everyone who knew her."
The EKU Volleyball Facebook page also published a tribute, though the specific language of that post has not been reported in detail. Mack had played only one season with the Colonels before transferring to Holy Cross, but the program still claimed her as one of its own.
Young athletes dying suddenly has forced families across the country to grapple with questions that often go unanswered. The family of champion skier Holden Parazette faced a similar nightmare after his death at 26 under unexplained circumstances.
Whether Mack was still actively rostered on the Holy Cross volleyball team at the time of her death, or had been placed on medical leave, remains unclear. No statements from Holy Cross coaches or athletic department officials beyond the team tribute have been reported.
Several details about Mack's death have not been made public. The specific location where she died, whether at a hospital, at home in Florida, or elsewhere, has not been disclosed. The exact mechanism of death, whether it was a direct result of the aplastic anemia, a complication from treatment, or another cause, is also unreported.
It is not clear whether her immunosuppressive therapy showed signs of working before her condition deteriorated. Her August 14 post suggested she believed the treatment had gone well, but the outcome speaks for itself.
Unanswered questions surrounding young deaths are not uncommon. An independent autopsy of college student Nolan Wells left his cause of death undetermined, with seven critical questions still unresolved, a pattern that leaves families searching for closure that may never come.
Severe aplastic anemia is rare and strikes without warning. It can affect anyone at any age, but it is particularly cruel when it finds a 20-year-old athlete in the prime of her competitive life. Mack went from playing Division I volleyball to fighting for survival in a matter of days.
Her volleyball career, though brief at each stop, spanned three programs, Cincinnati, Eastern Kentucky, and Holy Cross. She was a player willing to move and compete wherever the opportunity took her. That drive makes the abruptness of her death all the harder to absorb.
The parents of slain Pennsylvania soccer player Karoline Heintz described losing their daughter as "a parent's worst nightmare." Mack's family now lives inside that same phrase.
Amanda Mack spent her final public moments doing what too few people manage in a crisis: she told the truth about what was happening to her, plainly and without self-pity. The least the rest of us can do is remember her name.
