Few rumours I heard could be Khan v Judah on Mayweather undercard

[JazMerkin]

Maidana was the mandatory, his fight against Ortiz was an eliminator bout to determine the #1 contender for Kotelnik's belt, the same title Khan won

Amir Khan will make the first defence of his world title against Dmitriy Salita at the Metro Radio Arena in Newcastle on Saturday 5th December promoter Frank Warren confirmed today. Khan, who won the WBA light-welterweight belt in July with a punch-perfect performance over Andreas Kotelnik, faces a hard first defence against the new star of American boxing. Salita, the mandatory challenger for Khan's title, was born in Odessa, Ukraine, and moved with his family to Brooklyn, New York, when he was nine years old.

~ interim WBA World light welterweight title ~
Maidana down once in rd 1 & twice in rd 2. Ortiz also down in rd 1 & once in 6th.

in other words, making Maidana the #1 guy to get a shot at the title

Actually, no the WBA won't enforce a fight between it's respective 'champions' until they've both had the belt at least 6 months. They want to maximise the profits off them. Salita should have technically got the June fight with Kotelnik, so he was first in line for a shot at Khan.
