INDIANAPOLIS, Ind. – Indianapolis Colts punter Pat McAfee said he didn’t get a fine from the NFL for wearing custom-painted shoes to honor 9/11.

“Good news… @nflcommish is not a communist,” McAfee wrote on Twitter Wednesday, referencing NFL commissioner Roger Goodell. “No fine for my American cleats thus far. Good stuff Rog.”

McAfee wore the shoes against the Detroit Lions for the Colts’ season opener at Lucas Oil Stadium. He anticipated a fine for violating the league’s uniform policy and told ESPN it would be worth every penny if that was the case.

“I STAND with every citizen of the greatest country on earth,” McAfee tweeted before Sunday’s game with a picture of the shoes, which featured an American flag theme and the words “never forget.”

On Instagram, McAfee called 9/11 an “absolutely horrible day,” but he also recalled the sense of unity felt from coast to coast after the tragedy. He was 14 years old at the time of the attacks.

“I thank the heroic men and women of our military and our real life superhero first responders,” McAfee, well known to Colts fans for supporting charitable causes and the military. “Without you all, I understand that life would be much, much different.”

It's been 15 years since we saw first hand how America responds in a time of national crisis.. 1st responders sprinted into harms way in hopes of saving lives.. Young men and women across the country couldn't sign up for the military fast enough.. The heroes who were already enlisted, were eager to put boots on the ground in hostile land to bring some sort of vengeance to whoever attacked us.. Every citizen of our county had a sense of pride and unity for America.. Everybody was all in for one thing, eachother… 9/11 was an absolutely horrible day, we lost a lot of amazing Americans on that day and in the years that would come, we went to a war that still has yet to be finished.. I was 14 years old, and in the middle of all that negativity, what 9/11 did for me, was prove without a doubt, that America is the greatest country on earth.. Everybody had everybody's back.. Neighbor's who never talked to us came out and chatted.. Foes became friends.. We all FINALLY realized that we had something very obvious in common.. We're all in this together.. We were then.. And we are now.. It was a beautiful response, to an ugly act.. That's what I'll #NeverForget.. Today, just like everyday, I thank the heroic men and women of our military and our real life superhero first responders.. Without you all, I understand that life would be much much different.. Cheers #America
