The New England Patriots will wear black-ribbon logos on their helmets on Sunday in honor of the 26 victims of Friday's Connecticut elementary school tragedy.
The Patriots also will light 26 white flares during a moment of silence before Sunday night's game against the San Francisco 49ers.
The Patriots see Newtown as part of their New England base, and had a direct connection with Friday's tragedy.
The New York Giants also will honor the victims by having S.H.E.S. (Sandy Hook Elementary School) written on their helmets for Sunday's game against the Atlanta Falcons.
Giants coach Tom Coughlin also has S.H.E.S. written on the hat he will wear during the game.
The Kraft family, which owns the Patriots, also owns a box company, Rand-Whitney, that has a factory less than one mile from Sandy Hook Elementary School.
Rand-Whitney's parking lot was used Friday as a meeting area for media members after the tragic shooting at the school, a Patriots official said this weekend.
Coughlin also held a moment of silence for the victims at the team meeting at its Atlanta hotel on Saturday night. Many players were visibly moved, team sources said. Most found out what happened in Newtown coming off the practice field on Friday.
Giants wide receiver Victor Cruz told ESPN that he will honor one of the Sandy Hook Elementary School shooting victims by wearing the name of 6-year-old Jack Pinto on his gloves and cleats Sunday when the Giants play the Falcons.
Cruz said he got in touch with Pinto's parents to offer his condolences after hearing Jack was a fan. Cruz also said the family told him they were considering burying Pinto in a Giants jersey with Cruz's No. 80.
