A pregame ceremony at the Alamodome on Saturday ended in tragedy.

A member of the Air Force died after attempting to rappel from the rafters before Saturday’s game between Navy and UTSA. The event was part of UTSA’s annual Salute to Armed Forces & Veterans game.

The service member, whose name has not yet been disclosed by the Air Force, was injured at the stadium and died at a local hospital.

“We are deeply saddened by the incident that occurred at the start of tonight’s game,” UTSA said in a statement. “Our heartfelt thoughts and prayers are with the soldier who was affected, his family and his military colleagues.”

The service member was assigned to the 6th Combat Training Squadron, Detachment 2. The incident is currently under investigation.
