UPDATE, 2:15 p.m. August 11: This story now includes reactions from the Dallas Police Department and the Dallas Fallen Officer Foundation.

OXNARD, Calif. -- The Arm in Arm decal the Cowboys unveiled to open training camp won't be on their helmets when the club opens its preseason schedule Saturday at the Los Angeles Rams.

The Cowboys heard back from the NFL on Wednesday and were told by league officials they can't wear the decal during any preseason or regular-season games, executive vice president Stephen Jones said. Jones added that the Cowboys can wear the decal during training camp practices.

"Everyone has to be uniform with the league and the other 31 teams," Jones said after practice Wednesday. "We respect their decision."

The Dallas Police Department sent out a news release reacting to the news Thursday afternoon. In it, the department said the sentiment mattered more than the results.

"We appreciate the support of the Cowboys organization and its players," the statement said. "Their concern for the families of our fallen officers, the Dallas Police Department, and the City of Dallas is what matters most, and we know that support will continue for the immediate and long term future."

Meanwhile, the Dallas Fallen Officer Foundation told TMZ it was "extremely upset" by the NFL's decision.

"The NFL had an opportunity to be leaders and advocates for change in law enforcement," Sgt. Demetrick Pennie, president of the foundation, said.

"These are our friends and our loved ones ... it hurts to not have the NFL fully support us," he added.

Cowboys executives, players and coaches walked out onto the field for the first practice July 30 arm-in-arm Dallas Police Chief David Brown, Dallas mayor Mike Rawlings and family members of the officers slain in the ambush in Dallas last month.

Cowboys tight end Jason Witten helped initiate the idea for the unity ceremony and also wanted the Cowboys to wear the Arm in Arm decal on their helmets.

The Cowboys placed an Arm in Arm decal on the back of their helmets following the unity ceremony to show the club's support for the city and the officers' family members.

"There are so many wonderful, wonderful causes, the league has to be careful," Jones said earlier in camp about the possibility of wearing the decal in games. "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?"
