In honor of Veterans Day, it's time for us to take a moment to acknowledge the men and women who fight or have fought for our freedom.
Thanks to their bravery, we can sit back and enjoy the NFL—along with the rest of our freedoms—every Sunday.
With that said, let us pay particular tribute to several NFL players that have joined our armed forces in battle overseas.
Here are 10 NFL players who served our country.
