New Orleans Saints safety Kenny Vaccaro posted on Instagram that he will miss this Sunday's game against the San Francisco 49ers because of a concussion.
Vaccaro was injured during Sunday's 49-17 blowout over the Dallas Cowboys.
Vaccaro's helmet collided with the knee of Cowboys tight end Jason Witten while attempting to tackle him in the second half. He did not return to the game.
Earlier this season, Vaccaro sustained a concussion against the Buffalo Bills, but did not miss any games.
