Metairie, LA (SportsNetwork.com) - New Orleans Saints safety Kenny Vaccaro and tight end Benjamin Watson have been ruled out for Sunday's game against San Francisco due to concussions.
Both injuries occurred in the second half of last week's 49-17 win over Dallas. Vaccaro took a knee to the head from tight end Jason Witten while making a tackle, and Watson fell hard on his head when he tried to catch a pass in the end zone.
Vaccaro also suffered a concussion on Oct. 27 against Buffalo but did not miss any games.
Meanwhile, star tight end Jimmy Graham (elbow/foot), linebacker Curtis Lofton (hamstring/ankle) and defensive tackle Akiem Hicks (back) are all probable despite being limited in Friday's practice.
Safeties Roman Harper (knee) and Malcolm Jenkins (hamstring) joined defensive ends Tyrunn Walker (knee) and Cameron Jordan (ankle) as full participants in Friday's session and are also probable to play Sunday.
