D.J. Hayden, a 2013 first-round pick of the Raiders out of the University of Houston, was killed early Saturday in a car crash in Houston.

He was 33.

Hayden was one of six people who were killed in the crash, along with former Houston defensive back Zach McMillian and offensive lineman Ralph Oragwu. Former Houston defensive back Jeffery Lewis was injured.

“The Raiders Family is mourning the tragic loss of former cornerback D.J. Hayden,” the team said in a statement.

“The Raiders’ first-round draft pick out of the University of Houston in 2013, D.J. overcame a heart injury sustained in a college practice to play nine years in the NFL, including his first four with the Silver and Black. D.J.’s courage, perseverance, and dedication to his teammates will be fondly remembered by everyone who knew him.

“The prayers of the entire Raider Nation are with D.J.’s loved ones at this time.”

The Houston Chronicle reported that Hayden and his former teammates were in an Acura SUV when a Chrysler 300, which was traveling at a high speed, ran a red light and hit their vehicle.
