The Dallas Cowboys will not be permitted to place the "Arm in Arm" logo in support of Dallas-area police officers on their helmets during preseason or regular-season play in 2016.

Brandon George of the Dallas Morning News reported the news Wednesday. According to George, the Cowboys have donned the decal on their helmets throughout training camp in remembrance of the officers who were killed in a sniper attack in July.

Cowboys executive vice president Stephen Jones said the following regarding the league's rejection of the team's request, per George:

Everyone has to be uniform with the league and the other 31 teams. We respect their decision. There are so many wonderful, wonderful causes, the league has to be careful. If you allow one, then what do you do about every team that has a great reason to have something on their helmets? There are tons of things out there that need to be recognized. Once you open that Pandora's box, how do you ever stop?

"That decision doesn't take away from our emphasis on unity," Cowboys owner Jerry Jones said, per David Moore of the Dallas Morning News. Jones added that he was disappointed, but "we certainly respect and abide the wishes of the NFL," per Moore.

The Cowboys open their preseason schedule Saturday at the Los Angeles Rams, and they will host the New York Giants on Sept. 11 in their first regular-season contest of the campaign.
