Deontay Wilder to take out frustration on Chris Arreola

Deontay Wilder has vowed to take out the frustration of his postponed world title defence on Chris Arreola when the pair meet in the ring in Birmingham, Alabama at the weekend.

Wilder faces Arreola on Saturday night, live on Sky Sports, in the fourth defence of his WBC heavyweight title after a scheduled defence against Alexander Povetkin was called off due to a failed drugs test.

"I've wanted to hit somebody since May," said the undefeated knockout specialist, who boasts a record of 36 wins, with 35 by stoppage.

"Does he deserve the title shot, no he doesn't," added Wilder about replacement Arreola, who is attempting to win a world title at the third time of asking.

"But for this situation that we're in with the short notice, is he the perfect guy? You're right, he is."

Arreola (36-4-1-KO31) returns to the ring for the first time this year after his December win over Travis Kauffman was changed to a no decision following a positive test for marijuana.

The 35-year-old battled to a draw against Fred Kassi in his previous fight and beat Curtis Harper 15 months ago in his first bout after losing a title contest to Bermane Stiverne.

"This is my third opportunity," said Arreola, who was stopped on his stool after 10 rounds by Vitali Klitschko in 2009 in his first title shot. "I can't let this opportunity slip away.

"I respect Deontay. But once the bell rings, it's time to go fight and it's time to get that title. I want that title."

Wilder agreed a voluntary defence against Arreola in a bid to stay active in his quest to unify the division and to distance himself from the legal fallout that followed the postponement of the Povetkin bout.

The Russian, who tested positive for a trace of newly-banned drug meldonium, claims a new test has proved he was clean and his camp are now threatening to sue.

Wilder knocked out Polish challenger Artur Szpilka in his last fight in January.

"This is the longest stretch that I've been out of the ring and I'm anxious to get back in and continue my quest to become the undisputed heavyweight champion of the world," added Wilder.

"This is another fight in that process."

Wilder, however, is not planning on taking challenger Arreola for granted.

"When you're in the hurt business, you have no choice but to stay focused on the test that lies at hand because if you're not focused, you can get knocked out."
