Roby was carted off the sidelines in the first quarter and did not return. He had his right shoe off on the cart.
Roby's departure left the Saints short-handed at defensive back. Starters Paulson Adebo and Marshon Lattimore were ruled out prior to the game with injuries. Backup defensive back P.J. Williams was placed on injured reserve earlier in the season.
The Saints lost the game, 42-34.
