David Arquette Says Wrestling Days are Numbered After Incredible Comeback

David Arquette's professional wrestling career has been both mocked and admired, but above all else, it's been bloody hard work ... and he says it's coming to an end soon.

The actor's journey as a pro wrestler began way back in 2000, but as he points out on "TMZ Live" ... he didn't have a clue then about what it actually took to be successful.

Fast forward a couple decades, and a battle-worn David is flying higher above the wrestling ring than ever before -- even at 48 -- thanks to a commitment to various types of training and a devotion to the sport he's loved for a long time.

David says he's still an actor, though, and despite his remarkable comeback -- which is the subject of his new documentary -- he claims he's calling it quits soon.

That's probably a good thing, because as you may recall ... David was badly injured in a bloody match in 2018, and damn near died in 2019 after continuing to dish out and take beatings in the ring.

Arquette's daughter Coco wasn't too pleased with all of this, but he tells us she's come to accept and understand it more after seeing the documentary ... which he calls a "love letter to wrestling."
