On September 29, 2025, New York Giants owner John Mara, 70, announced that he has been following a treatment plan recommended by doctors for an undisclosed form of cancer.

Despite his diagnosis, Mara expects to remain active with the Giants as the team's president and CEO while undergoing treatment. Just last week, Mara was present at the Giants' practice facility in East Rutherford, New Jersey, when head coach Brian Daboll formally named rookie Jaxson Dart as the starting quarterback.
In his statement, Mara expressed gratitude for the "incredible support" he has received personally, professionally, and medically. "I'm fortunate to be surrounded by incredible support -- personally, professionally and medically," he said. "I'm committed to seeing this through to a positive outcome."
