Amir Khan will fight American Devon Alexander in Las Vegas on 13 December as the next step towards a meeting with undefeated Floyd Mayweather.
An announcement confirming the meeting, to be staged at Mandalay Bay Centre, is expected towards the end of the week.
Khan, 27, pulled out of a potential fight with Alexander in December 2013 in the belief that he may face Mayweather the following May.
Instead Mayweather opted for a meeting with Marcos Maidana.
Khan fought on the undercard of Mayweather's majority decision over the Argentine, beating Luis Collazo in impressive style.
It was Khan's third successive win since July 2012's defeat by Danny Garcia, improving his professional record to 29 wins and three defeats.
But he will instead face 27-year-old Alexander whose only defeats have come against Shawn Porter and Timothy Bradley.
In April Khan signed a deal to work with Al Haymon, the American match-maker who also advises Mayweather, in a bid to get to front of the queue for a lucrative meeting with Mayweather.
