Pittsburgh Steelers

1:00 PM PT -- The Seattle Seahawks and Tennessee Titans have followed the Steelers' lead ... and have both announced they will not be on the sidelines for the National Anthem prior to their game.

Steelers coach Mike Tomlin just announced his team won't be on the field for the National Anthem before their game against the Bears ... saying "we're not gonna be divided by anything said by anyone."

While he doesn't mention Donald Trump specifically, it's clear Tomlin is firing back at the president's call to fire the "sons of bitches" who kneel during the anthem.

The decision to stay in the locker rooms is "not to be disrespectful to the anthem, but to remove ourselves from this circumstance," Tomlin says.

Around 20 Baltimore Ravens and Jacksonville Jaguars players took a knee prior to their game in London earlier today ... with many other teams sharing plans to show signs of solidarity.

The baby business is BOOMIN' for Antonio Brown -- his girlfriend just gave birth to their brand new son!

The Pittsburgh Steelers wide receiver was able to get away from football Tuesday for the birth of Apollo Brown!

(It helps that today was a scheduled off day for Steelers players!)

Both baby and daddy looked great (Antonio had a big smile on his face) -- hopefully mom, Chelsie Kyriss, is doing well too.

It's AB's 5th kid -- 3 with Chelsie and 2 from a previous relationship.

James Harrison is the KING of crazy strength training videos ... but an NFL rookie might be comin' for the throne.

In the blue corner ... 39-year-old Steelers LB pushing a sled weighing OVER 1,800 POUNDS -- that's one plate for each year of his life.

In the red corner ... 22-year-old Falcons LB Duke Riley pulling an SUV weighing AT LEAST 5,500 POUNDS -- a 2017 Yukon Denali plus his buddy in the driver's seat.

James takes a few tries. Duke did his easy.

Keep in mind, though ... pushing is harder than pulling -- and Duke has wheels workin' for him too.

Pittsburgh Steelers cornerback Senquez Golson was stopped by TSA agents at an airport in Alabama after they found a handgun and bullets in his carry-on bag ... TMZ Sports has learned.

Maybe he was flying United???

Here's what we know ... the 2015 2nd round draft pick was going through security at Mobile Regional Airport around noon Wednesday when they found a Glock .45 caliber pistol along with 23 rounds of ammunition in the magazine.

There's a discrepancy over whether the gun can be considered "loaded" or "unloaded" since there was technically not a round in the chamber.

TSA alerted police and officers took the bag and escorted Golson out of the area.

Golson was NOT arrested. Instead, cops offered to hold the gun for him until he returned from his travels ... at which time he could pick it up.

How's that for southern hospitality?

Le'Veon Bell says he is working with the Steelers on a long-term deal ... and tells TMZ Sports he's confident something the two sides can work something out before the deadline.

Bell appeared on the "TMZ Sports" TV show on FS1 this week and admitted he has mixed feelings about being hit with the franchise tag ... but says he's hopeful he can strike a deal with his longtime team.

"We still going to work towards it," Bell said ... "Me and the Steelers want to work together. We're going to work towards a long-term deal leading up to the deadline (July 15th)."

"If it doesn't get done, it doesn't get done ... but I definitely think something will work and we'll see what happens."

Le'Veon Bell knows all about the diss track game (he recently went after Skip Bayless) ... and now the running back/rapper is offering up some hip-hop wisdom for Nicki Minaj.

The NFL superstar joined the guys on the "TMZ Sports" TV show (airs Thursday night on FS1) -- where he also talked about how he feels about getting hit with the Steelers franchise tag.

The good news -- lots of money. Bad news -- he wants more long-term security.

Joey Porter DEFINITELY got up close and angry with a bouncer before his Pittsburgh arrest -- but he did NOT rough the guy up ... and new security footage proves it.

Officials have finally released the video evidence in the case against the Pittsburgh Steelers assistant coach ... and while he certainly gets mad at the bouncer for not letting him in, we sure as hell don't see an assault.

Porter was initially charged with aggravated assault, simple assault, resisting arrest, disorderly conduct and public intoxication ... but eventually pled guilty to JUST disorderly conduct.

Pittsburgh Steelers linebackers coach Joey Porter just pled guilty to disorderly conduct stemming from a January altercation with security at a Pittsburgh bar.

Porter was initially charged with aggravated assault, simple assault, resisting arrest, disorderly conduct and public intoxication over the January 8 incident ... in which cops say Porter got physical with a bouncer after he was denied entry into the bar.

TMZ Sports obtained video of Porter jawing at cops during the arrest.

Prosecutors had previously announced they would reduce charges based on video evidence -- but clearly believed Porter wasn't exactly a perfect angel that night.

Nothing cures the Black and Yellow blues like a little bit of green -- so says Snoop Dogg.

The Pittsburgh Steelers superfan says he's still depressed and angry following his team's loss to the Patriots ... so he's self-medicating.

Antonio Brown says he's genuinely sorry for live streaming private moments from the Pittsburgh Steelers locker room ... explaining, "I let my emotions and genuine excitement get the best of me."

Brown got ripped by his head coach Mike Tomlin and QB Ben Roethlisberger for broadcasting the video ... which contained Tomlin referring to the Patriots as "a-holes."

The WR went to social media Tuesday night to issue his public apology.

"First, I'd like to take this opportunity to say that I'm sorry for my actions and behavior after Sunday's game," Brown wrote.

"I let my emotions and genuine excitement get the best of me, and I wanted to share that moment with our fans."

"It was wrong of me to do, against team and NFL policy, and I have apologized to Coach Tomlin and my teammates for my actions."

Pittsburgh Steelers head coach Mike Tomlin says he regrets referring to the Patriots as "a-holes" during his locker room speech ... and says Antonio Brown will be punished.

Tomlin just addressed the media about Brown's unauthorized Facebook Live video from the locker room after the Chiefs game ... and says it was "foolish, selfish and inconsiderate."

He noted the video was a violation of Steelers team and league policy.

Tomlin says Brown will be punished by the team -- but didn't expand on what the punishment will be. He hasn't spoken with Brown since the incident.

Tomlin says the locker room speech was supposed to be a private moment ... and moments like those shouldn't be shared.

As for his language in the video, Tomlin says, "As a parent, as a member of the community I take that very seriously. I issue an apology in that regard."

He also praised Tom Brady and said the Pats are a "great team."

Bill Belichick says he isn't on "SnapFace" or "InstaChat" ... and therefore doesn't give a crap about the cyber-insults the Steelers spewed on social media.

The Patriots head coach appeared on WEEI in Boston and was asked to respond to Mike Tomlin calling his team "a-holes" during a locker room speech that was live streamed by Antonio Brown.

Antonio Brown would get his ASS CHEWED over that locker room video if he was on the Pats ... at least, that's what Tom Brady insinuated ... saying, "I don’t think that would go over well with our coach."

The Patriots QB appeared on "Kirk & Callahan" on WEEI 93.7 FM when he was asked about Brown live streaming his head coach's locker room speech without Mike Tomlin's knowledge ... a speech that included Tomlin referring to the Pats as "assholes."

It's clear Brady believes Bill Belichick wouldn't have let that crap slide.

As for the A-holes comment, Brady didn't address that specifically -- but said Brown's decision to live stream a private moment wouldn't fly with the Pats.

"What’s done in the locker room should stay in the locker room.”

Steelers head coach Mike Tomlin called the Patriots a bunch of "assholes" during a locker room speech to his team ... a speech he didn't know Antonio Brown was streaming out on Facebook Live!!!

Just HOURS after crushing the KC Chiefs' Super Bowl dreams ... 38-year-old James Harrison was back in the gym -- getting ready for New England.

The guy is an absolute maniac ... busting out speed drills, power squats and back work.

By the way, Steelers coach Mike Tomlin (in a Facebook video streamed from the locker room) had estimated the Steelers jet wouldn't even land until 4 AM!!!!

New details from the Joey Porter arrest ... cops say the Pittsburgh Steelers assistant coach roughed up a bouncer at a South Side bar after the game Sunday night ... in a VERY boozy altercation.

According to the court complaint ... an off-duty cop arrived to the bar around 9:30 PM to find the former linebacker "standing over" the doorman.

The doorman told Porter, "Last time you were here, you threatened to kill me. You need to leave. You are not getting in."

At that point, cops say "Porter lunged at [the bouncer] and grasped [him] by his arms" ... and lifted him off the ground.

The off-duty officer says he rushed in and pulled Porter off the bouncer. The cop says Porter then grabbed HIM by the wrist -- and tried to plead his innocence.

He told the cop, while still grabbing him, "I'm not touching you."

The cop says Porter reeked of booze.

Eventually, Porter let go and was arrested. The cop says he was in fear that Porter was going to cause him "serious injury."

Porter was eventually booked for aggravated assault, simple assault, resisting arrest, disorderly conduct and public drunkenness.
