The Haskell Indian Nations University community is mourning the death of a 20-year-old male student who died suddenly after collapsing Friday while playing basketball, acting Haskell president Clyde Peacock said in a statement.

Justin McGee, of Ardmore, Okla., collapsed while playing in a club-sponsored tournament on campus. The university had a memorial service on campus for McGee on Tuesday evening at Haskell Auditorium.

“Justin was an excellent young man, a member of the Chickasaw Nation of Oklahoma and a redshirt member of the Haskell men’s basketball team,” Peacock said. “The university wishes to thank everyone at Haskell, especially staff and students, as well as the Lawrence community for their support during this difficult time.”

Funeral services were tentatively scheduled for Friday in Ardmore, according to the university. Haskell officials said McGee would have turned 21 this week.

“The university wishes to extend its sincere condolences to the family, friends and fellow students of Mr. McGee,” Peacock said, “and ask the community’s understanding while Haskell mourns the loss of this very fine young man.”
