Ricky Burns will take on talented Mexican Miguel Vazquez in a mouth-watering lightweight unification fight at Wembley Arena on March 16.
'Rickster' recently missed out on a fight with WBC champion Adrien Broner, because the proposed February date came too soon after a long camp for his December fight that was eventually scrapped.
However, promoter Frank Warren has pulled a rabbit out of the hat by matching IBF champion Vazquez (33-3) with his WBO title holder.
The light-punching Vazquez picked up the strap in 2010 and will be making his fifth defence, two of which came within six weeks of each other at the end of last year.
Scotland's Burns made two defences of his belt in 2012, scoring an impressive stoppage victory over Kevin Mitchell in September.
Vazquez campaigned at light-welterweight for much of his early career, suffering two early losses to then up-and-coming countryman Saul Alvarez.
The only other defeat on his impressive CV came against the still-unbeaten WBO light-welterweight Timothy Bradley.
"Ricky Burns has been very patient over the last few months, things didn't go his way in December," said Warren. "Then there was the chance to fight Broner but the fact is several weeks' notice is not adequate and therefore we couldn't go for that.
"But he insisted he wanted to fight the best, and hopefully he will set up a big fight in the summer against Broner, with adequate preparation, and three titles on the line.
"(But) he's a very difficult boxer to beat. He (Vazquez) brings a lot of problems that Ricky's got to find the answer to and I think it's going to be a really intriguing fight.
"But these are the fights he should have. This is where Ricky Burns should be. I'm pleased we managed to get it together."
