Monster trucks crash as part of their performance and they’re built to take a beating. That’s why it’s so unsettling to hear Dennis Anderson, creator of and arguably the sport’s most famous driver, was hospitalized after flipping his rig in the middle of a performance.

The North Carolinanewspaper reports that Grave Digger wiped out during a freestyle lap at the Raymond James Stadium in Tampa, Florida. As you can see from these fan-shot videos, the truck tried to do a backflip off a ramp but didn’t have enough speed to complete the stunt and landed on its roof instead of its wheels.

Grave Digger runs a 540 cubic-inch engine pushing 1,500 horsepower to four tires that are 66-inches tall. And another fun fact: those wheels are actually tied to the truck’s axles with steel braided cable to prevent them from flying into the stands in the event of a crash.

It doesn’t look like much of Grave Digger actually came apart in Anderson’s incapacitating crash in Florida, though. The truck had already shed its body by the time it made its failed flip, but the impact did look pretty brutal and direct.

Local news outlets are citing Monster Jam’s promotion company Feld Entertainment with a statement made Monday: “Medical care professionals tended to Anderson on site and then transported him to a local hospital for further evaluation. No further updates are available at this time.”

In that first clip, Anderson can be seen sitting upright and waving to the ground from a golf cart after exiting the wrecked monster truck, indicating he didn’t sustain any spine injuries. But no specifics on Anderson’s condition have been reported yet, other than what his son Adam Anderson posted to Instagram which so far have just been two vague statements saying Anderson the senior is “getting better.”

For those of you who don’t watch monster trucks regularly, first of all, . But even if you don’t follow this ridiculous(ly entertaining) sport I bet you’ve heard of Grave Digger. Anderson has been a mainstay of Monster Jam for pretty much as long as it’s been a commercial enterprise. In fact, Monster Jam just acknowledged Grave Digger’s a few days ago.

According to legend, the truck’s name comes from what Anderson use to say to people when they called his mud racing rigs junk: “I’ll take this old junk and dig you a grave with it!”

Here’s hoping Anderson has an expedient recovery.
