New Orleans Saints starting middle linebacker Alex Anzalone has been placed on injured reserve, according to multiple reports.

Anzalone is eligible to potentially return from IR later this season.

Kiko Alonso, who the Saints traded for before the season opener, will likely see increased reps.

News of Anzalone continues to a rough 24 hours for the Saints, who lost quarterback Drew Brees to a torn thumb ligament in yesterday's loss to the Los Angeles Rams.

Replacing Anzalone on the active roster is rookie defensive end Carl Granderson, who was recalled off the NFL's exemption list today.
