The NFL community is mourning the passing of Indianapolis Colts owner Jim Irsay.

Among them is Kansas City Chiefs Chairman and CEO Clark Hunt, who released this statement regarding Irsay on Thursday morning:

“My family and I are deeply saddened by the passing of Jim Irsay. Jim’s career in the National Football League spanned more than forty years, and in that time he became a trusted voice on league matters and a fixture of the local community in Indianapolis. He was a determined leader, a generous philanthropist, and at heart, a passionate football fan. Our thoughts and prayers are with the Irsay family and the entire Indianapolis Colts organization.”

Irsay’s father, Robert, owned the Colts from 1972-1996. Jim began his front office career as the Colts’ general manager in 1984. He assumed ownership in 1997 following Robert’s death. At 37 years old, Jim became the youngest NFL owner ever.

Similar to Jim and Robert, Clark took over as the Chiefs’ owner after the passing of his father Lamar in 2006, who founded the franchise as the Dallas Texans back in 1960. Lamar moved the team to Kansas City in 1963 and rebranded them as the Chiefs, owning them until his passing.

The Chiefs and Colts have had played each other in plenty of big games over the past few decades. Indianapolis got the better of K.C. more often than not during the 90s and early 2000s, especially in the playoffs. However, the Chiefs got a bit of revenge during the 2018 postseason, eliminating the Colts in the divisional round 31-13. Indianapolis is 18-10 all time vs. K.C.
