Dwayne Haskins, the Pittsburgh Steelers quarterback and 2018 Heisman Trophy finalist at Ohio State,

was struck and killed by a dump truck Saturday morning while trying to cross a highway on foot in South Florida, police said.

Haskins, who re-signed with the Steelers in March after serving as a reserve last season, was 24.

Haskins was trying to cross Interstate 595's westbound lanes, near the Fort Lauderdale-Hollywood International Airport in Broward County,

when the dump truck hit him, the Florida Highway Patrol said. The incident was reported shortly after 6:30 a.m., the patrol said.

Details about what led up to the incident were not immediately available. In recent days, Haskins was in South Florida working out

with some Steelers teammates, as captured in Instagram stories from Haskins and Steelers running back Najee Harris.

"I am devastated and at a loss for words with the unfortunate passing of Dwayne Haskins," Steelers head coach Mike Tomlin said in a statement released by the team.

"He quickly became part of our Steelers family upon his arrival in Pittsburgh and was one of our hardest workers, both on the field and in our community," Tomlin's statement reads.
