Saints' safety Kenny Vaccaro will miss the team's next game with a concussion, according to NFL.com's Ian Rapoport.
Vaccaro left Sunday's game in the third quarter after being hit in the head by the knee of Cowboys' TE Jason Witten and has since been diagnosed with a concussion. The rookie has the second-most tackles on the Saints' roster through ten weeks and is considered a top candidate for the defensive rookie of the year award.
Vaccaro will miss the Saints' game against the 49ers, and possibly the team's following game, a Thursday night contest against the Falcons. https://twitter.com/RapSheet/status/399948766528012289
