Heath Slater got his face busted open Saturday night ... and the wound was bone-deep!

WWE.com reports Slater suffered a gash over his right eye while wrestling at a WWE Live Event in Maine against Titus O'Neil, causing the referee to stop the match.

Ringside physician Dr. Stephen Daquino relayed details of the injury saying, "Heath has a six centimeter laceration above his right eye. It was quite open, right down to the bone. He got 18 sutures and hopefully that will close it up."

Slater tweeted about the injury afterward and said,"What we do isn't Ballet..."

There's been no indication that he'll miss any ring time, but that certainly is one helluva cut.
