Amir Khan has confirmed that his rematch against Lamont Peterson will take place on 19 May in Las Vegas.
American Peterson won the World Boxing Association (WBA) and International Boxing Federation (IBF) light-welterweight titles after beating Khan in controversial fashion in December.
Khan, 25, initially appealed against the loss, citing concerns about points deductions by the referee, but ultimately dropped his claim.
Khan announced the fight on Twitter  .

The pair will fight for a second time at Las Vegas's Mandalay Bay Hotel after their first match took place in Peterson's hometown of Washington, DC.
Richard Schaefer, chief executive of Khan's promoter Golden Boy, told Sky Sport News: "We have a deal, we are all set. This is going to be a big, and I mean a very big fight.
"The first fight was a terrific fight, an all-action fight, a lot of controversy, a lot of questions surrounding it so this one here is hopefully going to clear up all these question marks."
The WBA ordered a rematch earlier this month, claiming there were "multiple irregularities" in the first fight, and giving Peterson 180 days to agree terms with Khan for a new contest.
Bolton fighter Khan was initially unhappy with referee Joseph Cooper for deducting two points for pushing, and the way he judged the fight.
In the days after the bout, Khan also used his Twitter account to ask a series of questions about a "mystery man" who was seen at ringside talking to Michael Welsh, the WBA scoring supervisor, during the fight.
The "mystery man" was subsequently named as Mustafa Ameen who attended the fight as a guest of the IBF but had no official role that evening.
In an exclusive interview with BBC Sport last month, Ameen claimed he was only correcting mistakes and that Welsh was complaining of feeling unwell.
