On Friday afternoon, a frustrated Khan indicated that he believes that Mayweather already has chosen Maidana, whose manager, Sebastian Contursi, could not be immediately reached for comment.
But on Friday evening, Leonard Ellerbe, CEO of Mayweather Promotions, disputed Khan's claims during an interview with Fighthype.com.
Golden Boy CEO Richard Schaefer, during an interview with mlive.com, also indicated that a deal with Khan had not been reached.
In an earlier afternoon interview with RingTV.com, Schaefer said fans might expect Mayweather's announcement to be made on his Twitter account, the same place where fans chose Khan over Maidana in accordance with a request from Mayweather, whose 37th birthday is on Feb. 24.
"I think that for the past few fights, Floyd has announced them on Twitter, so I anticipate that this is going to continue. I think that he has, like, five million followers now, which is amazing," said Schaefer. "He just has a huge following and a huge fan base. Floyd Mayweather's name, Floyd Mayweather's celebrity status, it's all bigger than ever, and you see it with the speculation concerning who he's going to fight next. We've seen it getting started back in November when reports were coming out of England that the Khan fight was done.
"It has been that way, pretty much, ever since, for the last three and a half months. The speculation on who he's going to fight has been very intense and I think that we are days away from Floyd making his announcement, and we all know that it's going to be the Super Bowl of boxing again on May 3, because when the eyes of the world — not the boxing and the sports world — but the eyes of the entire world will be looking at the highest paid athlete in the world performing, that's what people are looking forward to."
In the mean time, said Schaefer, much of the Golden Boy spring schedule is on hold for major fights, beyond a announced 175-pound unification bout between IBF beltholder Bernard Hopkins and WBA counterpart Beibut Shumenov that will happen on April 19 in Washington, D.C.
"We know that we have April 19 from The D.C. Armory. We're going to spend some time putting the undercard together. We have some ideas, and, hopefully, within the next few days, we'll have something to report. There are a lot of great fights that we are working on putting together," said Schaefer.
"We just have to see what's going to happen when Floyd makes his decision known, and we'll have to see how that comes along. Then we'll slot in the other fights. We are looking at doing an event on April 26, which will be a double-header, and then we have May 3, so we'll just have to see which fights will go where."
There has been wide speculation that Mayweather would choose Khan, who stated publicly in December that he had signed to face Mayweather.
Maidana could also be in line for a rematch with Adrien Broner, whom he dethroned as WBA 147-pound titleholder by unanimous decision in December.
Mayweather was last in the ring in September, when he beat Canelo Alvarez by majority decision for the RING and WBC 154-pound championships.
In May of last year, Mayweather unanimously decisioned Robert Guerrero in defense of the WBC 147-pound title he had earned by dethroning Victor Ortiz via fourth-round stoppage in September of 2011, cementing his status as RING welterweight champion as well.
Mayweather is also the WBA's reigning 154-pound titleholder, having earned that belt by unanimous decision over Miguel Cotto in May of 2012.
