Le'Veon Bell has told his teammates on the Pittsburgh Steelers that he plans to report on Labor Day.

Bell has been holding after not yet signing the franchise tag of $14.5 million for 2018. Bell wanted a long-term deal.

Bell did the same thing last year when he did not officially report until Sept. 4, which was six days before the 2017 season opener.

Bell still started in Week 1 in 2017.

The Pittsburgh Steelers have built a structure to cover one of their three fields in an effort to prevent spying.

The structure consists of four black pillars about two stories high and for practice sessions the team can raise an attached giant black tarp.

"I'll leave that somewhat mystical for you guys to hypothesize about the origins of that and its use, and at some point we'll address it the right way," Mike Tomlin said. "I know how it is, man. This is interesting times, drones and so forth. We do what we've got to do to prepare and get ready to play to have a level and fair competitive playing field."

Ben Roethlisberger has entered the NFL's concussion protocol after suffering a hit in practice.

Roethlisberger went down during a 7 shots segment of practice, according to multiple reporters on the scene.

Roethlisberger went down after he rolled out and ran into Marcus Gilbert as the offensive tackle was blocking linebacker Keion Adams.

Roethlisberger was briefly on the ground before eventually getting up. 

The NFL is investigating the Pittsburgh Steelers after they used a deflated football during the third quarter of Thursday night's preseason game against the Philadelphia Eagles, according to a report.

The incident in question came with Mason Rudolph in at quarterback for the Steelers.

The Pittsburgh Steelers have sent Antonio Brown to be evaluated for an injury.

Mike Tomlin did not specify the body part that was injured but classified the ailment as "just a day-to-day, minor injury. Nothing to speak of."

Brown was expected "to be fine in a few days," a source told ESPN's Adam Schefter.
