TOP Rank promoter Bob Arum is visibly upset over eight-division world champion Manny Pacquiao’s failure to have his rotator cuff surgery checked and undergo rehabilitation in the United States.

Pacquiao was scheduled to have his right shoulder checked some two weeks ago, but didn’t  make the trip, prompting Arum to tell The Standard/BoxingScene.com that Pacquiao “drives me crazy.”

We raised the possibility of a trilogy with Timothy Bradley since the World Boxing Organization had stripped Floyd Mayweather Jr. of the title and installed 'Desert Storm' as the new champion following his interim-title fight victory over Jessie Vargas.

This would give Pacquiao a chance to regain the title.

“I’m not even thinking about a next fight for Manny unless he comes over and does his rehab,” Arum said bluntly.

ABS-CBN’s Dyan Castillejo told The Standard/BoxingScene she had spoken to Pacquiao, who had no idea when he would return to Los Angeles for rehab, but said he could raise his right arm although he did suffer some pain.

Meanwhile, the camp of the undefeated pound-for-pound king doesn’t seem to care about losing the WBO welterweight title.

After being stripped of the WBO belt he won in the “Fight of the Century” against Pacquiao and failing to pay the WBO the $200,000 sanction fee, the reaction of Mayweather Promotions’ CEO Leonard Ellerbe was what one would expect.

“Floyd will decide what, or if any, actions he will take. But in the meantime, he’s enjoying a couple of hundred millions he made from his last outing (against Pacquiao) and has zero impact on anything he does,” Ellerbe told ESPN.com.

In an effort to soften the critical comments, Ellerbe said that Mayweather “has a great deal of respect for each and every organization, as he has always had in his 19-year career, but he will not be dictated to by any organization or person as it relates to his decision-making.”
