Kell Brook's world welterweight title fight against IBF champion Devon Alexander will now take place in Atlantic City on Saturday, 18 May.
The bout has been postponed twice because of injuries to both fighters.
Brook said: "It's been a frustrating wait, but now I'm ready to get in there on 18 May and bring that title home."
The 26-year-old Brook has an unblemished record of 29 wins from 29 fights, while two-weight world champion Alexander, who is the same age, has won 24 of his 25 bouts.
Their fight will be on the same card as IBF light-welterweight title holder Lamont Peterson's showdown with the WBC's interim champion Lucas Matthysse.
