President and CEO John Mara stands on the sidelines during pregame of a game between New York Giants and Indianapolis Colts at MetLife Stadium on Sunday, Dec. 29, 2024.

New York Giants co-owner, president and CEO John Mara announced on Monday that he was diagnosed with cancer.

"I have recently been diagnosed with cancer and have been following the treatment plan recommended by an outstanding team of doctors," Mara said in a statement via the Giants' account on X.

"I'm feeling strong and optimistic, and I'm committed to seeing this through to a positive outcome. I plan to remain active with the team throughout my treatment, and I'm fortunate to be surrounded by incredible support – personally, professionally and medically.

"I ask that you respect my privacy and my family's privacy at this time."

Mara, 70, has been the president and CEO of the Giants since 2005. The franchise was founded by his grandfather, Tim Mara, in 1925 and the Giants ownership has remained in the family ever since.

Wellington Mara, father of John, died of lymphoma in October 2005.
