Joe Calzaghe's WBO super middleweight defence with Peter Manfredo Jr in Cardiff has been put back to 7 April
The delay from 3 March is believed to be due to logistical problems at the Millennium Stadium venue, with a Six Nations rugby game there on 17 March.
The fight will be 34-year-old Newbridge man Calzaghe's 20th WBO defence, and could be his last show in Wales.
Manfredo, 26, finished as runner-up on US TV series 'The Contender' and holds a record of 26-3 (12 KOs).
Calzaghe's 100% record stands at 42-0 (31 KOs), and he has been WBO champion since 1997
Enzo Maccarinelli will defend his WBO cruiserweight title on the undercard and Amir Khan will feature on a bill that promoter Frank Warren promises will be the biggest ever staged in Wales.
If Calzaghe triumphs, a potential summer "mega-fight" with middleweight king Jermain Taylor remains a possibility.
The American WBC and WBO champion took a unanimous decision over Kassim Ouma in Little Rock, Arkansas, on Saturday.
When asked about a potential Calzaghe bout afterwards, he said: "I'll face whoever wants to fight. I'm the type of person who'll fight anyone. I just want to feed my family."
Taylor plans another fight in the first half of next year, but a Calzaghe showdown remains a possibility in late summer
