Nurse!

Tim McGraw slayed at his concert over the weekend ... and one of the casualties was a chick in the audience he accidentally laid flat.

Tim was making his big entrance at the Tacoma Dome in Washington Saturday night when a female fan got in his path and hit the concrete floor ... and hard. From what we can see, she was no worse for wear ... a security guard checked her and she seemed fine.

You may recall another incident back in 2014 ... when Tim slapped a woman during an Atlanta concert who looked like she was either grabbing for his jeans or his junk.

Two drivers in the Indy 500 were lucky to walk away -- let alone be alive -- after a super gnarly crash that flipped one vehicle over multiple times.

Racers Scott Dixon and Jay Howard collided into one another Sunday during the Indy 500 race in Indianapolis ... which sent Scott's car flying into the side rails and tore it to pieces.

After getting checked out by docs onsite ... both drivers were surprisingly left unscathed.

Scott was also in good spirits afterward in what could have been a deadly moment.

Erika Jayne wasn't being stuck-up on the finale of "Dancing with the Stars" like some fans accused her of being -- she skipped the final group performance because she needed surgery.

The 'Real Housewives' star is at an L.A. hospital Friday to have surgery to fix an upper body tear she suffered during the show. Sources with 'DWTS' tell us ... Jayne felt like something was wrong during a dance in early April.

Doctors confirmed the injury, but we're told she pressed on without telling anyone ... because she didn't want to play the sympathy card. She was eliminated shortly thereafter.

Doctors told her she should stop all dancing after that, which is why she sat on the sidelines -- on top of a unicorn -- during the finale.

We reached out to ABC about Erika's injury ... they had no comment.

"Alaskan Bush People" star Matt Brown needed 9 staples in his head after an explosion in his fridge landed him in the hospital.

Our sources in Alaska tell us the accident happened Tuesday night in Matt's Hoonah, AK crib. Apparently, he'd filled a mason jar with gunpowder and cannon fuse, and stored it in his fridge. Doesn't seem like the smartest move, but if you haven't seen the show ... the Browns march to the beat of their own drum.

Lo and behold ... the mason jar exploded, and blew the fridge door off its hinges, and into Matt's head.

He went to a hospital, got stapled back together and was released. Now, we know what you're thinking, and no ... this wasn't a stunt for the show. 'ABP' wasn't shooting at the time.

Queen Elizabeth trekked across England to visit some victims of the Manchester Arena face-to-face ... and she looked spiffy doing it.

The Queen showed up Thursday to the Royal Manchester Children's Hospital dressed in a blue suit -- and a bright orange hat -- to visit 3 young girls who were injured in the explosion.

Looks like the hospital staff also got some face time with Elizabeth ... who thanked them for treating the victims with a royal well-wish.

Ezekiel Elliott was in a car accident early Monday morning ... and sustained a minor head injury after the vehicle he was riding in was rear-ended in the Dallas area ... TMZ Sports has learned.

After hitting up a charity event thrown by Tony Romo and Clutch bar Sunday night, sources tell us Zeke was the passenger in a car that was rear-ended by another vehicle ... 'causing the Cowboys star to hit his head.

We're told the car was "rear-ended pretty bad."

The Cowboys confirmed the accident ... and said Elliott -- who missed OTAs all week -- was being held from practice strictly as a precaution.

Christina El Moussa was questioned by Child Services after her toddler fell in their pool.

Sources close to the family tell TMZ Christina and Tarek's 1-year-old, Brayden, was under the care of the nanny Monday when he fell into their pool. We're told she swooped the child up quickly and he was never unconscious.

Christina returned home and when the nanny told her what happened she took her child to a hospital as a precaution ... to make sure there wasn't any water in his lungs.

Brayden checked out fine, nonetheless we're told Child Services interviewed Christina and the nanny at the hospital and determined no action was necessary.

Brayden is back home and things are back to normal.

12:25 PM PT -- We're told the alligator has died. RIP.

This poor alligator never saw it coming -- a motorcyclist mowed over the nearly 11-foot gator on a Florida highway and it's now listed in critical condition.

The incident went down just after midnight Friday in Wimauma, FLA when a 27-year-old man driving his Suzuki GSX-S collided with a gator crossing the highway. The guy flew off the bike and was airlifted to a nearby hospital. The gator was missing chunks of body parts.

The man's expected to make a full recovery. As for the gator, though, boots and belts are in its future.

Normani was attempting to jump into a split when she landed funny on the foot of her partner, Val Chmerkovskiy ... which rolled her right ankle. Happens in basketball all the time, but always looks painful.

Normani and Val are currently in first place and are frontrunners to win the 'DWTS' mirrorball trophy.

A cyclist riding in New Orleans got hit by a stray bullet from a shooting nearby ... and the whole thing was caught on video.

Christopher Weiss was cruising along with his cycling club in NOLA, when all of a sudden he shrieked in pain and had to pull over. As it turns out ... he'd been shot.

One of his fellow riders caught the entire encounter on their mounted bike camera, as another attended to his wound. It's pretty crazy -- you can see the exact moment he was hit ... even though you don't hear gunfire.

Ex-Louisville star Kevin Ware says breaking his leg at the height of his college career "sucked for me" -- and says he's 100% confident he'd be in the NBA if not for that terrible moment.

24-year-old Ware is currently playing overseas and believes he still has the talent and drive to make it to the league ... but says he knows that fateful moment changed the trajectory of his career.

The moment made international headlines -- when Ware gruesomely snapped his right leg through the skin while Louisville was playing Duke in the Elite 8 ... a game watched by millions.

Ware says he believes everything happens for a reason -- but his dream is to play with the best in world and he's asking for NBA teams to give him a shot.

Kim Zolciak just shared an up close and personal post-surgery photo of her son's injured face after he was gnarled by a dog ... and the attack left several marks.

Kim posted a pic Tuesday of 4-year-old Kash Biermann, with a long caption thanking fans who sent prayers during the ordeal. She says ... "Kash has healed up incredibly and has perfect vision in his left eye. Stitches on his water line, and his eyeball was never touched! God is Good!"

Kim also thanked the doctors who operated on her son.

As we reported ... Kash had to undergo surgery after he was bitten in the face. At the time, Kim cited his injuries as "traumatic." She's never said anything more about the attack or whose dog was behind it.

Great to see Kash is doing better now.

Machine Gun Kelly must really love the tour life ... 'cause he's fighting through serious pain to make sure his fans see him live.

MGK performed Saturday at the Carolina Rebellion music festival in NC, and was obviously still suffering from his busted sternum. He repeatedly clutched at his chest during his set, but powered through it to keep up with his band. The pounding bass from the speakers can't help.

MGK's rep tells TMZ ... even though he's hurting, Kelly doesn't want to put off any more shows than he already has -- and he's doing his best to heal in his downtime.

We broke the story ... Kelly's recovering after filming a new movie, "Captive State" where he got punched 65 times.

A porn star shooting an underwater ad for a sex cam company was attacked by a shark and badly bitten.

Molly Cavalli dropped down under water into a shark cage wearing a hot white swimsuit and her presence apparently enticed a 10-foot lemon shark.

Check out the vid ... Molly panics when the shark approaches, and next thing you know she's screaming as she clutches her bloody foot.

The crew pulled her up to safety, but the shark had done some serious damage ... it took 20 stitches to close the wound.
