British lightweight Anthony Crolla has been forced to withdraw from his scheduled bout with John Simpson on March 1 in Glasgow.
Crolla had been hoping to further improve his world title credentials with a win against the Scot, but a cut suffered in training means that the Mancunian won't compete again until April 19.
The 27-year-old has been replaced by John Murray, who only returned from a two-year hiatus from the ring in November with a comfortable victory over Spain's Michael Escobar.
Ricky Burns's WBO lightweight title bout with unbeaten American Terence Crawford headlines the bill at the SECC.
