A pair of special teams players for the Giants said following Sunday's win over the 49ers that they were aware of kick returner Kyle Williams and his history of concussions. "The thing is, we knew he had four concussions," Jacquian Williams said. "So that was our biggest thing, was to take him out of the game." New York linebacker Michael Boley was asked about Williams on Tuesday and denied any targeting. "When you're playing, you don't think about someone's past injuries or what they had wrong with them," Boley said. "Obviously, if something was wrong with them, they wouldn't be on the field if it was that bad."
