Florida Highway Patrol spokesperson Lt. Indiana Miranda confirmed the accident on westbound Interstate 595. Haskins was pronounced dead at the scene.
Miranda didn’t say why Haskins was on the highway. The accident caused the highway to be shut down for several hours.
“He was just walking on the highway and got hit,” Miranda told The Associated Press.
Haskins was training in South Florida with other Steelers quarterbacks, running backs and wide receivers.
“I am devastated and at a loss for words with the unfortunate passing of Dwayne Haskins,” Steelers coach Mike Tomlin said in a statement. “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. Dwayne was a great teammate, but even more so a tremendous friend to so many. I am truly heartbroken.
“Our thoughts and prayers are with his wife, Kalabrya, and his entire family during this difficult time.”
