During the Saints' game against the Lions, an NFL official suffered a severe leg injury when he collided with Alvin Kamara on the sideline. In the second quarter, Kamara, running towards the first-down marker, was pushed out of bounds by a Detroit defender, causing him to crash into the game official. The official crumpled in pain, with his leg bending awkwardly inward. Trainers quickly attended to him, immobilizing him on a backboard and transporting him off the field. The NFL has not provided an update on his condition as of Monday morning. However, it was reported that the official, Nick Piazza, suffered a dislocated knee and a fractured fibula, with intact blood vessels. Surgery is expected next week.
