Overview

  • The Giants published Mara’s statement on Sept. 29, in which he said he feels “strong and optimistic” and is following a treatment plan set by his doctors.
  • Mara attended Sunday’s 21-18 win over the Chargers and said he plans to remain involved in team operations throughout his care.
  • The announcement drew widespread support across the NFL, including messages from teams, former Giants figures and league media.
  • Mara has served as president and CEO since 2005 and holds key league roles, including chair of the NFL Management Council executive committee and long-time Competition Committee member.
  • The Mara and Tisch families continue to control the franchise as a 10% minority sale to the Koch family awaits owner approval, with no expected impact on day-to-day operations.
