Pittsburgh Steelers quarterback Dwayne Haskins was killed early Saturday morning after he was struck by a dump truck while walking on a South Florida interstate, authorities said. 

Haskins was attempting to cross the westbound lanes of Interstate 595 on foot when he was hit by a dump truck around 6:37 a.m., according to the Florida Highway Patrol. Haskins was pronounced dead at the scene, and authorities said it was "unknown" why he was walking on the interstate.

"This is an open traffic homicide investigation," Florida Highway Patrol spokeswoman Lt. Indiana Miranda told Fox News. "No further information will be released until the investigation has been closed."

Westbound traffic on the interstate was shut down Saturday morning, and drivers were advised to see alternative routes, the FHP said.

The former Ohio State standout was reportedly in Miami training with Mitch Trubisky, who was signed by the Steelers last month to a two-year deal. 

Haskins posted several photos on his Instagram account in recent weeks. NFL stars have commented on the posts since the loss.
