The cause of death for Pittsburgh Steelers quarterback Dwayne Haskins has been revealed.

According to an autopsy report from the Broward County Medical Examiner obtained by E! News, the 24-year-old NFL star died from "multiple blunt force injuries" after being struck by a dump truck while walking on a South Florida highway on April 9. The manner of death has been ruled an accident.

At the time of his death, Haskins had a blood alcohol level between 0.20 and 0.24, over Florida's legal limit of .08, and tested positive for ketamine and norketamine, per a toxicology report acquired by E! News.

Before his death, the quarterback—who was in Florida to train with his team—and his teammates went to dinner. Haskins and a relative then went to a nightclub and reportedly "drank heavily," according to a police investigation report obtained by E! News.

Haskins ran out of gas while traveling on I-595 and left on foot to find a nearby gas station. He attempted to cross the westbound lanes of the interstate, where there was oncoming traffic, and was struck by a dump truck. He was pronounced dead on the scene.
