Jeff Horn’s trainer, Glenn Rushton, admits that last weekend they suffered a setback when Ray Robinson was knocked out Yordenis Ugas.

Ugas and Robinson were fighting in a final IBF welterweight eliminator at the Mandalay Bay in Las Vegas, as part of the Danny Garcia vs. Brandon Rios undercard.

Horn had planned to use Robinson as one of their main sparring partners for the upcoming mandatory defense of the WBO welterweight championship against Terence Crawford, which is scheduled for April 14th in Las Vegas.

Rushton is now evaluating their options to bring in a new sparring partner to replace Robinson, who was viewed as a very good selection for them.

He was shocked at the reckless way Robinson fought in that ring that night.

The trainer admits that it hasn't been easy to secure sparring partners who resemble the fighting style of Crawford, but they have several names that he won't disclose at the moment.

“Now that he has lost that fight that has certainly thrown a spanner in the works,” Rushton said to the Weekend Australian. “I am just weighing up all of the options but I am trying to find the best I can. But there is not a lot of southpaws. There is not all that many that are right up there (in quality).

“We had all agreed to wait to see how he (Robinson) came through this fight and we would go from there. He didn’t fight really well at all. You have to say ‘where is his head at?’ You don’t want a fighter to come out here and their head is in the wrong place, they are still licking their wounds and they are not very motivated.

“If he had won he would have been very motivated. I believe he would have gone to No 2 (ranking) if he had won. Then we would have had a different ball game — a guy highly motivated to become world champion. His only losses were to Shawn Porter and then an early one in his career. So very credible losses. His form read beautifully. I think he was the last guy to beat Terence Crawford actually when they were amateurs a long time ago.

“He had all the right form and very, very similar style. Now I am scouring the world looking for who I can get. It is tough. There are not a lot of guys who move exactly like Crawford. You have to try to find someone as talented as he is and on the way up. There are a couple I am looking at but I don’t want to name names because I haven’t spoken with them yet.”
