Deontay Wilder’s brother Marsellos brutally KOed hours before Luis Ortiz rematch

DEONTAY WILDER’S brother Marsellos was brutally knocked out just hours before the WBC Champion defended his crown.

The heavyweight king’s younger sibling, 30, suffered the second KO defeat of his career as he fought on the undercard of Wilder vs Luis Ortiz II at MGM Grand Garden Arena.

He was in control of the scheduled six-round cruiserweight clash when he was caught by a huge left hand from Dustin Long.

And it knocked Marsellos senseless as he lay prone on the canvas out cold.

Referee Jay Nady instantly waved an end to the fight 1:51 into the fourth.

That was 37-year-old Long’s third straight win, taking his record to (3-1-2, 3 KOs).

Meanwhile, Wilder’s own three-fight winning run (all by unanimous decision) has come to a crashing end after he first lost in January to a fourth round TKO to journeyman William Deets.

He bounced back from that setback with a first round KO against Mark Sanchez in March before earning a unanimous decision over Tyler Vogel in June.

Wilder Jnr then overcame Jamaican Nicoy Clarke in a cruiserweight bout 40-36, 40-36 and 39-37 in a fight filled with holding and grappling in August.

However, the result of his bout with Sanchez was later changed to a no-contest by the Texas Combative Sports Program in April.

That was a result of Wilder failing an unspecified test it administered.
