Just after the 2 minute 40 second mark, Anderson tried a backflip but there wasn't enough rotation, and it landed on the lid, hard.
Anderson, 56, is one of the most successful monster truck drivers in history, having competed in Monster Jam since 1982. The Kill Devil Hills, North Carolina native has four World Finals titles, three in the racing category and one in freestyle.
During last weekend's show in Tampa, Florida, he attempted a backflip that went awry with the truck landing upside down. Anderson was helped from the wreckage by paramedics before being transported to a local hospital for further evaluation
Just in case they are wondering, yes, I sure will drive it for the Grave Digger crew until Dennis is well enough. I got it, don't worry. I'm expendable, and will go to the outer limits to put on a great long show for the fans.
