12 years ago was one of the most gruesome, NSFW matches in WWE history

There's a reason we don't see chair shots like this anymore.

Eddie Guerrero and Joh Bradshaw Layfield had one of the most brutal rivalries in recent memory, and this match served as a reminder of just how bloody their brawls were.

It all started with the referee knocked out, when JBL grabbed a chair and blasted Guerrero over the head with it. The champ, Guerrero, started pouring blood out of his forehead before equalizing with a few nasty chair shots of his own after dropping the contest due to disqualification.

Check out the action above.
