Arizona Cardinals cornerback Jeff Gladney has died after being involved in a car accident in the early hours of Monday morning.

The Dallas County Sheriff's Office announced that at 2:28am, first-responders attended a scene where two cars collided.

One other person died in the crash. The second victim has not been identified as the incident remains under investigation.

The Cardinals confirmed Gladney's death in a brief statement.

"We are devastated to learn of Jeff Gladney's passing. Our hearts go out to his family, friends and all who are mourning this tremendous loss," the statement read.

Gladney, 25, was a first-round pick in the 2020 NFL Draft by the Minnesota Vikings after a glittering college career at TCU, where he became close friends with Philadelphia Eagles wide receiver Jalen Reagor.

Responding to the news, Reagor tweeted out: "Lost my brother, my best friend, my right hand man… ain't too much more I can take man damn! R.I.P Jeff Gladney, brother watch over me please."

J.J. Watt was one of several of Gladney's Cardinals teammates to also pay their respects, saying: "Horrifying news to hear this morning. Just tragic. Rest in peace Jeff."

Gladney's former team, the Vikings, also offered their condolences.

"We are saddened by the tragic death of former Viking Jeff Gladney," the franchise said. "Our hearts go out to his family and friends, as well as the Arizona Cardinals organisation and Jeff’s current and former teammates and coaches who are mourning his life lost much too soon."
