Notes: Wilder and Arreola test negative

Wilder TKOs Arreola despite injuries (1:13)

Despite suffering a broken right hand and a probable tear in his right biceps in the fourth round, Deontay Wilder defeats Chris Arreola via eighth-round TKO to improve to 37-0. (1:13)

A few notes from around the boxing world:

  • Heavyweight titleholder Deontay Wilder and challenger Chris Arreola tested negative in their Voluntary Anti-Doping Association blood and urine tests in conjunction with their July 16 title fight in Birmingham, Alabama, according to the Alabama Athletic Commission. Wilder knocked out Arreola in the eighth round.

  • Light heavyweight Eleider "Storm” Alvarez (19-0, 10 KOs), 32, a Colombia-born, Montreal-based contender, will face late replacement Robert Berridge (27-4-1, 21 KOs), a 31-year-old southpaw from New Zealand, on Friday night (Spike, 9 ET/PT) at the Videotron Centre in Quebec City. Alvarez was supposed to face former world champion Chad Dawson, but he suffered a training injury. Alvarez, as long as he wins, looms as the mandatory challenger for the main event winner between world champion Adonis Stevenson (27-1, 22 KOs) and Thomas Williams Jr. (20-1, 14 KOs). Alvarez-Berridge is scheduled for 10 rounds at a contract weight of 180 pounds.

    "I prepared to face a southpaw in Chad Dawson and Berridge is also left-handed, so adapting will be easier," Alvarez said. "I tip my hat to him for accepting this challenge with only a 10 days’ notice. For sure, I am really disappointed in Dawson's withdrawal, but these things happen that you cannot control. I'm still happy to get in the ring."

  • Ukrainian light heavyweight contender Vyacheslav Shabranskyy, 29, who is based in Los Angeles, will headline Golden Boy’s “LA Fight Club” card on Aug. 19 (Estrella TV) at the Belasco Theater in downtown Los Angeles. Shabranskyy (16-0, 13 KOs) will take on Oscar Riojas (10-5-1, 3 KOs), 32, of Mexico, in an eight-round bout. Shabranskyy made a name for himself in December with his 10-round decision against Yunieski Gonzalez.

    “He is a fearless warrior whose inner strength matches his physical strength and skill," Golden Boy Promotions CEO Oscar De La Hoya said of Shabranskyy. "Slava, as we call him, is a future star of the sport headed toward a world championship, and I've been pleased with his continued ascent as he rises to the challenge every time he steps in that ring. I'm proud to call him a Golden Boy fighter."

  • Junior bantamweight titlist McJoe Arroyo (17-0, 8 KOs), 30, of Puerto Rico (24-1-1, 16 KOs), will travel to Bacoor, Philippines, to make a mandatory defense against Jerwin Ancajas (24-1-1, 16 KOs), 24, of the Philippines, on Sept. 3 at Strike Coliseum. Arroyo will be fighting for the first time since winning a vacant 115-pound world title by 10th-round technical decision against Arthur Villanueva last July. Ancajas has won his last 11 fights in a row.
