Detroit’s 32-28 win over New Orleans on Sunday was delayed in the first half when Saints running back Alvin Kamara was tackled into a member of the chain crew, taking out the sideline assistant’s legs.

The injured official was carted of the field and the chain crew operated with one fewer person for the remainder of the game.

Jared Goff passed for 213 yards and two TDs for the Lions (9-3), who raced to a three-touchdown lead and then held off a valiant comeback bid by the Saints. New Orleans (5-7) fell one game behind first-place Atlanta in the league’s weakest division, the NFC South.

After falling behind 21-0 in the first quarter, the Saints pulled as close as 24-21 late in the third. The Saints also had the ball at midfield with a chance to take the lead in the final three minutes, but turned the ball over on downs when Jameis Winston threw behind Chris Olave.

The Saints lost quarterback Derek Carr in the fourth quarter to back, shoulder and head injuries. Carr was hurt on a penalized hit by Bruce Irvin, who drove the weight of his body into the quarterback.
