It's impossible to fathom the tragedy that occurred in Newtown, Connecticut.
On Sunday, the NFL honored the families and victims from this horrific incident, which cannot justifiably be described in words.
According to Dan Hanzus of NFL.com, "In the wake of the tragedy, the NFL has asked home teams to observe a moment of silent reflection prior to the national anthem before this weekend's games."
Ahead, we look at Week 15 tributes around the pro football landscape.

The tragedy affected Victor Cruz of the New York Giants on a more personal level. Per an article by Dan Graziano of ESPN.com:
Cruz told ESPN's Josina Anderson that he got in touch with the Pinto family to offer condolences after he'd heard Jack had been a fan of his. The family told Cruz that they were considering burying Jack in a Cruz jersey.
Without question, a classy move by a classy player.

Along with the child on the left, we also see a No. 66 jersey in between Austin Spitler and Derrick Shelby. For you NFL history buffs, that's legendary Dolphins offensive lineman Larry Little.
Little is in the pro football Hall of Fame and was part of Miami's perfect season in 1972.
