The fire department was called to a construction site after the 4,100 pound slab fell off the back of a truck and landed on the construction worker's pelvic area.
That's when, investigators say, the other workers sprang into action and managed to pick up the concrete.
The victim is in the hospital with a broken hip. He was last reported in stable condition.
