Mayes' ground and pound attacks looked even more vicious because of all the blood pouring from Sipe's head.

Once on the ground, Sipe became a blood mess.

In the second round a huge cut opened above Sipe's eye.

Heavyweight Don’Tale Mayes battled through a bloodbath to beat Mitchell Sipe on Dana White’s “Tuesday Night Contender Series” but still did not land a UFC contract.

Sipe went into the bout with a 4-0 MMA record and a bad-boy reputation and was dominating the first round.

But a ghastly gash above Sipe’s eye and the rivers of blood that streamed down his face made any grappling or submission holds almost impossible, and Mayes landed a huge knockout in round two.

A wicked elbow from 6-foot-6 Mayes ripped the flesh from Sipe’s face, but he managed to stay on his feet for a while.

However, once on the canvas, the blood was streaming into Stipe’s eyes, and it became a matter of time before Mayes’ thunderous blows caused the ref to jump in.

With just seconds of the second round remaining, the bout was stopped with a blood-soaked Sipe on his back and Mayes pounding away at his mangled face.

“It feels wonderful. I felt good,” Mayes said. “Walking around at 270 pounds was slowing me down.

“I lost the weight, lost about 15 pounds and I had better cardio.”

Four fighters were handed UFC contracts from the show, but Mayes was not one of them.
