A few notes from around the boxing world:

• Heavyweight Chris Arreola has been added to the Premier Boxing Champions card, headlined by junior featherweight titlist Carl Frampton against Alejandro Gonzalez Jr., on July 18 (CBS, 4 p.m. ET) at the Don Haskins Center in El Paso, Texas. Arreola, 34, will face an opponent to be determined in a 10-round fight that could be part of the telecast depending on how long other fights go. Arreola was supposed to fight on the June 6 Robert Guerrero-Aron Martinez PBC card in Carson, California, but soreness in his elbow kept him off the show. Arreola (36-4, 31 KOs), of Riverside, California, is coming off a knockdown, drag-out war with Curtis Harper on March 13, which Arreola won by eight-round decision.

"I'm about excitement, and I know that everyone who comes out in El Paso and everyone watching on television will get an entertaining fight,” said Arreola, a two-time world title challenger.

• Featherweight Joseph Diaz (16-0, 10 KOs), a 2012 U.S. Olympian from South El Monte, California, is over the strained right biceps he suffered in a May 9 victory on the Canelo Alvarez-James Kirkland undercard in Houston. Diaz, 22, will be back in the ring July 11 at the Los Angeles Memorial Sports Arena on the Mauricio Herrera-Hank Lundy undercard, Golden Boy announced. Diaz will fight an opponent to be determined in a 10-round bout. Diaz’s bout is not slated to be part of the HBO Latino broadcast (11 p.m. ET/PT), which includes Herrera-Lundy and a junior welterweight bout between Michael Perez and Sharif Bogere.

• Featherweight prospects Antonio Nieves (12-0, 6 KOs) of Cleveland and Stephon Young (13-0-1, 5 KOs) of St. Louis will meet in an eight-round bout that will serve as the co-feature for the main event between Oakland’s Andre Ward (35-5, 20 KOs) and Paul Smith (35-5, 20 KOs) of England on June 20 (BET, 10 p.m. ET) at Oracle Arena in Oakland, Roc Nation Sports announced. Ward, the super middleweight champion, is returning to the ring after a 19-month layoff and will be facing the former two-time world title challenger in a nontitle bout at a contract weight of 172 pounds.
