Khan was once tentatively slated to face IBF welterweight titlist Devon Alexander in December at the Barclays Centre in Brooklyn.
However, Khan decided to bypass Alexander (25-1, 14 KOs) and instead focus on a potential match against Mayweather.
The Ring “Fighter of the Year” in 1998 and 2007, Mayweather is now considering Argentinean Marcos Maidana as an opponent.
"What he has done to Amir Khan is absolutely disgraceful, whether he ends up fighting him, or he doesn't," said Arum, 82, who Mayweather refuses to negotiate with. "They have twisted the kid in the wind. Mayweather should be ashamed of himself. He's not going to sign the contract. I think he will fight Maidana."
“King Khan” most recently exited the squared circle in April after outscoring Mexican Julio Diaz.
Flattened by a left hook in the fourth and staggered by the same punch in the eighth, 10th and 11th rounds, Khan was lucky to escape without losing to Diaz (40-9-1, 29 KOs).
Comparatively, Maidana (35-3, 31 KOs) earned a unanimous decision over Adrien Broner to capture the WBA welterweight title on December 14.
Mayweather will easily outclass either Khan or Maidana this spring.
A middling boxer and human chandelier, Amir Khan should feel honored that Floyd Mayweather is even twisting him “in the wind.”
