Police said chances are low that the driver even realized he had hit anything.
The truck was described as having a white tractor and a yellow container, with the letters MSC on it.
The victim's wife was at the scene and asked for the driver to return and speak with police.
"Please come forward, I'm not gonna press charges or nothing, I just want you to come forward, show your face," Marta Rojas said. "Be a man, be a woman."
The victim was out of surgery Tuesday night and is recovering.
