Montgomery (undisclosed) was carted off the field at practice Wednesday, Amie Just of The New Orleans Times-Picayune reports.
The reason for Montgomery's worrying departure from practice remains undisclosed. The sixth-year veteran has been taking the majority of his reps in training camp at wide receiver, and with Michael Thomas (ankle) set to miss regular-season action and Tre'Quan Smith (undisclosed) currently not practicing, the Saints can ill afford to lose any more pass catchers.
