Kim Pegula, co-owner of the Buffalo Bills and Sabres, is seeking treatment for undisclosed health issues. According to a statement released by the Pegula family on Tuesday, “Kim is undergoing medical treatment as a result of some unanticipated health problems.

We are quite grateful for the development she has made in recent days. She is surrounded by a world-class team of medical professionals. We respectfully request that you keep Kim and our family in your prayers and respect our desire for privacy.”

Pegula Sports and Entertainment is led by Pegula, who is 53 years old. She is the first woman president of both an NFL and NHL team, and she controls the Bills and Sabres’ corporate operations.

After buying the Sabres in 2011, Kim and Terry Pegula, 71, bought the Bills in 2014. Kim Pegula is a member of the NFL’s workplace diversity committee and has been a vocal supporter of increased diversity in the NFL and NHL.

Pegula is also a member of the NFL’s Super Bowl and large events advisory committees, as well as the business ventures and foundation committees.

Pegula was born in Seoul, South Korea, and was adopted by a Canadian family in Fairport, New York, east of Rochester, when she was five years old. She later went to Houghton College after growing up in western New York.

The Buffalo Bandits and Rochester Knighthawks of the National Lacrosse League, as well as the Rochester Americans of the American Hockey League, are also owned by the Pegulas.

An agreement was reached this year on a new $1.4 billion stadium that will keep the Bills in Orchard Park, New York, for the foreseeable future with a 30-year lease.

The Pegulas visited the site of the racist attack that killed ten people in an East Buffalo supermarket last month with commissioner Roger Goodell.

Jessica, Kelly, Matthew, Michael, and Laura Pegula are the Pegulas’ five children. Kim Pegula’s family did not provide any additional information about her condition.

“What [Kim and Terry Pegula] have done for me, for my family, for this team, for this city and western New York — just being there for them, all of us collectively offering our prayers and support and giving them the privacy that they need, is important during this time,” Bills coach Sean McDermott, who was hired by the Pegulas in 2017, said Tuesday.
