Gruesome aerial shot of the blood-stained floor shows just how brutal UFC 189 was

Jesus.

If you're queasy, look away right now.

We knew UFC 189 was full-on. We know MMA isn't for the faint-hearted and we all saw some of the frightening hits that went on during the biggest night in UFC history.

We just didn't know it was this bad.

Most of it was probably left over from the Robbie Lawler and Rory MacDonald brawl - a fight for the ages - but the accumulative total was a mat in the Octagon almost painted red.

During the main event, Conor McGregor and Chad Mendes wrestled and grappled and rolled around the floor together over what almost looked like a sea of blood.

Paul Kimmage already hit out at the barbaric nature of MMA after McGregor's interim title victory and a shot like this won't sway his attitude.

But it shows how much it meant to the fighters.
