MGM Grand, Las Vegas - The final press conference for the Manny Pacquiao vs. Timothy Bradley HBO Pay-Per-View rematch, taking place this Saturday night at the MGM, was moving along at a friendly pace.

But, Top Rank's CEO Bob Arum closed the press conference with a huge verbal bang.

Arum has been upset with the MGM's promotion of Saturday's rematch. During the week, Arum voiced his anger to several reporters - regarding the venue's heavy display of promotional items related to the upcoming Floyd Mayweather Jr. vs. Marcos Maidana Showtime Pay-Per-View on May 3rd.

During the end of the press conference, with a stunned Richard Sturm [President of MGM Grand Entertainment] sitting right beside the podium, Arum unleashed his fury.

"I'm not going to say it....the hell with it - I know the Venetian would never make a mistake like this, they knew what fight was scheduled in three or four days and they wouldn't have a 12-1 fight all over the building that's going to take place in three weeks from next Saturday. That's why one company makes a billion dollars a quarter and the other hustles to pay it's debt [referring to the MGM]. There it is, say it like it is," Arum said to a stunned crowd.

A moment earlier, Arum was talking to Bradley near the podium and said - "Why don't you ask the guy who's picture is all over the building on when he's going to fight somebody real." - taking direct a jab at Mayweather. Bradley laughed a replied - "I'll let you ask him that."

Speaking to BoxingScene earlier in the day, Arum stated - "How many more 10-1 fights can the MGM sell to people? [Golden Boy Promotions CEO Richard] Schaefer can say whatever he wants about the fights, but all you have to do is go and look at the odds at the Race & Sportsbook to see it's not a competitive fight."
