Sunday will mark the 15th anniversary of 9/11, and the NFL has pretty big plans for honoring the lives of those lost in the tragic terrorist attacks in 2001.

A few specific New York players will be paying tribute too. Giants wide receivers Odell Beckham and Victor Cruz will both wear cleats honoring those who lost their lives as well as first responders.

According to Jordan Raanan of ESPN, Cruz and Beckham will wear specially-designed cleats both during warmups and during the game, all of which were designed by Kickasso like Picasso.

"It's a special cleat for a couple reasons. I mean opening day is on 9/11," Troy Cole, owner of Kickasso said. "And Odell wanted to pay tribute to the heroes of 9/11, and not toward the tragedy aspect, with the falling building and the heroes all around kind of helping and saving people. That is why it's kind of special and going to be pretty cool."

UnderArmour also gave members of the Giants gloves to wear for the game.

There could be some interesting things to watch with respect to how NFL players handle pregame behavior in Week 1.

Sunday is obviously a very important day in America's history. Remembering 9/11 is something the NFL makes sure to do, because of the close connection between the tragedy and football, particularly in New York.

But there is some controversy occurring with pregame behavior these days, thanks to Colin Kaepernick and other NFL players choosing to sit or kneel during the national anthem.

Should players do so on Sunday, it's possible they will be met with a less-than-enthusiastic response.
