Former Indianapolis Colts running back Zurlon Tipton died on Tuesday after a gun accident, according to the Wayne County Medical Examiner’s office. The accident occurred around 9:30 a.m. when one of two guns contained in a duffel bag went off while the 26-year-old was removing the bag from his vehicle at a car dealership in Roseville, Mich., Detroit’s Fox 2 reports.

A recording of the 911 call from the dealership describes the incident as “unintentional.”

“A gentleman just shot himself in the stomach,” the man’s voice explains. “His gun went off.”

“He’s down on his back right now,” the man continued, noting he heard just one shot. “He is awake … He is talking.”

It is unclear how quickly Tipton’s state deteriorated. However, according to Fox 2, police thought Tipton would survive.

Wayne County Medical Examiner spokesman Lloyd Jackson told The Washington Post that Tipton will undergo a full autopsy on Wednesday morning. Roseville police also expect to release further information about the incident on Wednesday, according to a spokeswoman.

The type of gun involved in the incident is as of yet unknown. Tipton was arrested in December on a charge related to an assault rifle.

Tipton, a former standout at Central Michigan, came to the Colts as an undrafted free agent in 2014. He played 16 games before being waived at the end of the 2015-16 season. He was not a member of any NFL team at the time of his death.

Despite Tipton’s past troubles, Colts long snapper Matt Overton told ESPN’s Mike Wells, “Zurlon was a dude you rooted for. … His personality was contagious. … He was the hammer when on the field. He will always be our brother, he is family. Today is a tough day for many. Prayers go out to his family during this difficult time.”
