NFL official to have surgery following horror injury after collision with Saints running back Alvin Kamara

TV cameras showed Piazza clutching at his leg, which looked to have bent into an awkward angle, and shouting in pain before cutting away.

The game stopped for several minutes while Piazza was attended to by medical staff before he was stretched from the field and then taken to hospital. The chain crew operated with one fewer member for the rest of the game.

The Saints said that Piazza had undergone an MRI on Monday and was seen to by an orthopedic doctor. He was found to have suffered a fractured fibula and a dislocated knee but his “blood vessels remain intact” and would have surgery likely next week.

“He appreciates the many well wishes and the continued care he continues to receive,” the Saints said.
