"The Sandlot" star who has been charged with felony assault helped beat a grad student within an inch of his life ... according to new legal docs.

Michael Vitar, who played Benny "The Jet" Rodriguez in the flick, allegedly attacked the 23-year-old USSB student on Halloween night.

According to a search warrant obtained by TMZ, 2 of Vitar's friends, both of whom are firefighters, spotted Samuel Chang passing out candy in the street of his gated L.A. community. The firefighters suspected Chang was passing out tainted candy and confronted him.

The warrant claims the 2 firefighters began beating on Chang, restraining him with a chokehold. The legal docs claim Vitar -- now a firefighter as well -- joined in, mid beating.

The warrant says the beating was so bad Chang's pulse stopped and the firefighters had to get their gear and revive him.

Chang was taken to the hospital with horrific injuries, including burst blood vessels in the eye, bleeding on the brain, kidney failure and hemorrhaging due to suffocation.

Chang had recorded the audio of the beating on his cell phone, and cops believe they can hear Vitar say, "I got the legs."

The student says he smelled alcohol on the breath of one of the firefighters. The firefighters told cops they believed Chang was under the influence of PCP, but doctors found no drugs in his system.

A guy with a bum kidney who worked at Kleinfeld Bridal -- the store featured on TLC's smash hit, "Say Yes to the Dress" -- claims he was savagely beaten on the stairs going into the store, and he's filed a bridal brutality suit.

William Martinez claims he worked for Kleinfeld from 2011 - 2014 and everything was hunky dory until his last year on the job, when he was hospitalized with kidney problems and it left him unable to do the various physical tasks he was assigned.

Martinez says he went to one of the managers -- Manny -- and said he needed to be reassigned to clerical duties, but Manny kept making him do heavy lifting and later, told him to just "go the f*** home."

According to the lawsuit, Martinez told Manny he was going to file an HR complaint, and Manny responded by pushing him into a chair. Martinez finally left but when he came back he says Manny, with the help of a posse, took his cane away and beat the crap out of him.

Martinez says he was hospitalized and then fired by HR.

He's suing under the Americans with Disabilities Act for all sorts of money.

Sources close to McKee tell us her mom and husband Josh rushed her to a hospital Wednesday night near their home in Miami, Oklahoma. We're told she was violently throwing up all night.

She is still there, and doctors are trying to stabilize Mackenzie's sugar levels.

Mackenzie has been training and dieting to compete in her next figure competition and that could have been a factor.

Pacman Jones can hold on to that Oscar ... or Grammy ... 'cause Antonio Brown's father insists his son is NO ACTOR ... and didn't fake hurt after taking that shot from Vontaze Burfict.

TMZ Sports spoke with Eddie Brown who tells us he has already checked in with the Pittsburgh Steelers receiver to make sure he's okay after taking a shot to the head during Saturday's playoff game.

"He is doing well. I talked to him but I didn't go into detail. I just wanted to make sure he was okay. That was my biggest concern as a father and parent."

We asked what he thought about Pacman accusing his son of faking hurt -- and Eddie told us the thought of Antonio bluffing an injury is simply unfathomable.

"It's not in his character. I don't have to defend him because you can just look at his track record. Check his and then check the track record of the ones accusing him ... he's taken big hits before and he's gone right back to the huddle."

We also asked if he thought Burfict should be punished by the league for the hit:

The San Francisco 49ers booted a fan and his service dog from Levi's Stadium which made the fan have a seizure ... according to the lawsuit he's now filed against the team.

James Hilburn says he and his Alaskan malamute, Bear, had no problems entering the Niners-Cardinals game on November 29 -- the ticket taker let them in, no questions asked. In his suit, Hilburn says he suffers myoclonic dystonia ... which causes seizures. Bear is trained to alert him and people nearby when one is about to hit.

In the lawsuit, James says once he entered the staidum, police and security guards surrounded him and said Bear was not allowed to be there -- and the stressful situation triggered a seizure.

TMZ Sports obtained video Hilburn's friend shot, and you can hear Bear yelping a warning. Police and stadium staff attempted to get a shuttle to pick them up, but Hilburn declined. He did end up suffering, and had to be hospitalized, according to his lawyer Mark Thomas.

Hilburn wants the team to pay for violating the Americans with Disabilities Act.

We reached out to the 49ers who told us they do not comment on pending litigation.

Rob Kardashian was diagnosed with diabetic ketoacidosis ... this according to our Kardashian sources.

TMZ broke the story ... Rob was taken to an L.A. hospital Sunday after feeling terrible all weekend.

Our sources say after a battery of tests, Rob was diagnosed with diabetic ketoacidosis, a serious complication of diabetes that occurs when someone's body produces high levels of blood acids, or ketones.

Rob had no idea he was diabetic, and it's a good thing he took precautionary measures. If untreated, the condition can lead to a diabetic coma.

But there's good news ... our Kardashian sources say the doctors told Rob if he eats well and leads a "healthy lifestyle," he can actually get his diabetes, which is type 2, under control and potentially have it go into remission.

Rob is back at home and resting, and this may be just what the doctor ordered -- literally -- to get him back on the right path.

David Foster just put all the doubters to rest ... saying Yolanda Foster's battle with Lyme disease is very real and very serious.

In a statement obtained by TMZ ... Foster backs his ex, saying, "it is so frustrating to see headlines questioning her chronic debilitating illness." Foster's addressing several reports that have suggested Yolanda might not actually be as sick as she claims.

Foster gives Yolanda even more props ... saying he's proud of Yolanda's fight and how brave and open she's been in finding a cure for the disease.

It makes sense ... TMZ broke the story -- David's been the one to foot all of Yolanda's medical bills -- even after their split, so you gotta assume he knows what's going on with her health.

Poison's drummer was on the Sirius XM show "Eddie Trunk Live" when he revealed his diagnosis, saying it all started over the summer when he had a cold and a sore throat. He says doctors at USC eventually did a biopsy and discovered a tumor at the base of his tongue.

Rikki says the human papillomavirus is behind his diagnosis -- "This is very similar to [Iron Maiden's] Bruce Dickinson, very similar to Michael Douglas, similar to [Aerosmith's] Tom Hamilton, as far as I know."
