Green Bay Packers

9:23 AM PT -- A rep for BWW told us ... "Buffalo Wild Wings takes food preparation, service and quality extremely seriously and we are looking into this situation. We’ve reached out to Jared Cook and our suppliers for more information."

Green Bay Packers tight end Jared Cook knows how Brad Pitt felt at the end of the movie "Seven" -- 'cause he opened up a box and found a decapitated head inside!!!

The 29-year-old says it all went down at Buffalo Wild Wings on Tuesday -- when he opened up his box of lemon pepper wings and saw a decapitated HEAD staring back at him.

"Tongue, eyes, and beak all present. With extra seasoning," Cook said.

When he raised the issue to staffer, Cook says he was told, "Sorry unfortunately this happens because the chicken is fresh."

And the Academy Award goes to ... someone other than Clay Matthews.

But hey, at least when it comes to reenacting scenes from classic movies ... the Packers star gets an A for effort.

News that Aaron Rodgers is axing dairy -- INCLUDING CHEESE!!! -- didn't sit well with Wisconsin congressman Sean Duffy.

We caught the U.S. Rep walking around in D.C. when we clued him in on the Packers QB's new diet plan. Check out the vid ... Sean couldn't believe his ears when we told him the NFL superstar's eliminating dairy. Y'a know ... cause milk/cheese = protein.

Rodgers told ESPN he wants to follow a stricter eating regimen following knee surgery in January ... sparking a near MELTDOWN among faithful cheeseheads.

Eddie Lacy went all Rocky Balboa (from "Rocky IV") in his off-season workout -- training in the snow TWICE A DAY with his P90X trainer Tony Horton.

Horton -- who created P90X -- spent months helping the Green Bay Packers running back trim down for the season ... and judging by the last video we shot of Lacy, it worked. Dude's pretty ripped now.

So, we asked Horton how he got Lacy back to form -- and the training regimen he revealed is pretty hardcore ... including some snow shoveling sessions in Jackson Hole.

Horton says Lacy was a natural when it came to working out -- but there was ONE exercise the guy couldn't stand.

The mystery is over.

Chris Pratt says he takes FULL RESPONSIBILITY for torching Aaron Rodgers' steak on a couples trip earlier this month -- falling on the sword in the biggest celebrity meat story since "Kim Kardashian, Superstar."

Somebody get Eddie Lacy some tape ... 'cause the dude is RIPPED UP!

Check out the GB Packers running back proudly displaying his guns in a tank top at LAX this weekend -- showing everyone he's been busting his ass in the gym this offseason after his coach called him out for being overweight.

We broke the story ... Lacy hooked up with the creator of P90X back in February (after the guy came on "TMZ Sports" and offered to whip Lacy into shape) ... and you can already see the results.

John Kasich is throwing SHADE at Aaron Rodgers ... and it all went down live Tuesday night at a town hall event right in the middle of Packers country.

Long story short ... Kasich was asked who he'd pick as his running mate if he actually got the nod -- and that's when he took the dig at the Green Bay Packers quarterback.

Clearly, Kasich was trying to show the people of Wisconsin that he keeps up with the Packers -- but dissing Rodgers in CheeseheadLand?

He's definitely slimmed up ... but Eddie Lacy says he refuses to put an exact number on his weight loss because "I don't do scales."

The Green Bay Packers RB touched down at LAX this weekend -- so, we had to ask about his off-season workout regimen with P90X creator Tony Horton.

Lacy says he's feels great ... and he doesn't need a stupid scale to prove it.

But at some point, the Packers are gonna make him get on a scale right??

Eddie Lacy is no dummy ... and knows if one of the biggest fitness gurus in the country offers to whip your butt in shape -- you listen.

TMZ Sports has learned ... Lacy's people have been in touch with P90X creator Tony Horton -- after Tony offered to PERSONALLY train the Green Bay Packers running back.

Horton -- who's trained all sorts of huge stars, athletes (Ray Lewis) and even politicians (Paul Ryan) -- previously told TMZ Sports he already has a game plan to help Lacy drop his extra weight and get into the best of shape of his life before next season.

Now, Lacy's people have confirmed the two sides have touched base in the hopes of working something out ... though no agreement has been struck yet.

Horton says he doesn't want to undermine Green Bay's training plan for Lacy -- but instead, he wants to work WITH the team to get Eddie where he needs to be.

"The Packers will get him ready for the season. My job will be to get the weight off and help him eat better."

With GB Packers coach Mike McCarthy ripping Eddie Lacy for being out of shape this season -- there's one man who says he can save the embattled running back ... THE P90X GUY!!!!

In case you missed it ... Lacy was heavily criticized for appearing larger than usual when he arrived to camp to kick off the 2015 season ... and never seemed to drop the excess weight.

McCarthy says Lacy needs to get his ass in shape for next season ... or else.

Enter fitness mega-mogul Tony Horton -- creator of the world famous P90X program -- who says he would LOVE the opportunity to PERSONALLY train Lacy this off-season ... because he's confident he get real results.

Horton tells us he's already got a 3-month bootcamp style plan in mind -- which would get Lacy back into top form.

"Time is ticking ... so it's time for him to step up."

BTW, a bunch of NFL stars have raved about P90X -- including Ray Lewis.

Seems Aaron Rodgers is still bitter about the NFL Draft ... calling it a "train wreck of 'expert' analysis and awkward hugs."

So, why would the Super Bowl champion QB be so salty on the league's biggest offseason moment?

It probably stems from the 2005 draft ... when some experts projected Rodgers to be the #1 overall pick ... but instead, he tumbled all the way down to #24.

Cameras focused on Aaron during the slide ... and you can tell he was pissed.

Green Bay Packers cornerback Jarrett Bush was arrested in Northern California for public intoxication following an alleged brawl outside of an Italian restaurant ... officials say.

According to the Vacaville Police Dept., cops responded to Evelyn's Big Italian Restaurant early Sunday morning after getting a call about a "large fight."

When officers arrived to the scene, most of the crowd dispersed ... but Bush remained ... and refused to leave. Cops say Bush "continued to create a disturbance" and was eventually arrested.

He was transported to a nearby jail ... and officers say that's when he began to chill out and became cooperative with police.

Bush was eventually released without charges.

Clay Matthews ain't no Milli Vanilli ... TMZ Sports has learned the Green Bay Packers star laid down REAL LEGIT VOCALS for his cameo in "Pitch Perfect 2" ... and apparently, it came out pretty good.

In fact, all of the football players who have a cameo in the movie hit up a recording studio and flexed their god-given pipes for a scene in the upcoming movie ... at least, that's what Jordan Rodgers told us on "TMZ Hollywood Sports."

Jordan -- a QB in the Canadian Football League -- also happens to be the younger brother of Aaron Rodgers ... and says he got the role as a "honorary" member of the Packers.

"So the first day we were there, we recorded in the studio," Rodgers says ... "so this will be our real voices."

"They said they were gonna make us sound good ... but not too good. They don't want it to be unrealistic."

So, who was the best singer of the bunch? Check out the clip.

Aaron Rodgers and Olivia Munn had a double date with a semi-famous friend Wednesday night ... an actor who's pretty recognizable from a famous Quiznos commercial ... TMZ Sports has learned.

The Green Bay Packers QB and the "Mortdecai" star hit up Matsuhisa in Beverly Hills ... along with actor Tim Rock and his date.

Tim (who's been friends with Munn for a while) is an actor who's been in a bunch of stuff ... but we remember him from that Quiznos ad where the oven was like HAL 9000 from "2001: A Space Odyssey" (awesome btw).

Wonder who paid for dinner?

Not even a Chicago Bears fan could hate this video of Aaron Rodgers paying a surprise visit to four kids ... who lost a parent in the military. Grab the Kleenex.

The Green Bay Packers quarterback met with 3 sisters -- Alexis, Starr and Kylee -- and a young man named Dylan ... to spotlight the great work done by Camp Hometown Heroes in Wisconsin.

The girls didn't seem to be big football fans, but you have to see Dylan freak out when he realizes Aaron Rodgers has shown up.
