The Saints will be without safety Kenny Vaccaro in next week's game against the 49ers.

Vaccaro sustained a concussion Sunday night in a blowout win against the Cowboys. Vaccaro broke his own news, posting the message on his personal Instagram page.

Vaccaro suffered the concussion while trying to tackle Cowboys tight end Jason Witten.
