Junior welterweight contender Sergey Lipinets will not get a mandatory crack at champion Julius Indongo, according to the Russian boxer's manager Alex Vaysfeld.

Lipinets is the mandatory challenger under the International Boxing Federation (IBF) and the sanctioning body has ordered Indongo to meet his mandatory obligation.

Indongo has become a top force at the weight after his two most recent fights. Last December, he traveled to Russia to score a sensational first round knockout of undefeated Eduard Troyanovsky to capture the IBF, IBO world titles. Then last month, he went over to Scotland and dominated Ricky Burns over twelve rounds to secure the WBA belt as well.

According to Vaysfeld, he expects Indongo to finalize a fight with WBC, WBO champion Terence Crawford - which is going to leave the IBF title vacant.

Last weekend, Indongo traveled over to the United States and sat ringside as Crawford stopped Olympic gold medal winner Felix Diaz at New York City's Madison Square Garden.

Afterwards, Crawford's promoter, Bob Arum of Top Rank, said a unification with Indongo was their top priority for Crawford's next fight. Both boxers have expressed the desire to face each other next.

When or where Indongo-Crawford would take place is unknown. Arum stated that his company would not sit back and wait for HBO to come up with an available date for the fight. He plans to move forward with Crawford's career, with or without HBO.

"The fight with Indogo won't happen, he will fight with Terence Crawford. The IBF will appoint a contender [to fight Lipinets] and we expect that fight will take place in August," Vaysfeld said.

Indongo has an undefeated record of 22 victories (11 by KO) and no losses, while Lipinets has a record of 12 wins (10 by KO) and no losses.
