Former world heavyweight champion Samuel Peter is out of Saturday night’s clash with Alexander Ustinov.
The 35 year-old, who held the WBC title from 2008 until 2009, was scheduled to compete for the just the second time in four years on the Roy Jones Jr v Enzo Maccarinelli undercard in Moscow, has been withdrawn this week without explanation.
‘The Nigerian Nightmare’ stepped away from the ring following a 2011 knockout loss to hard-hitting Finn Robert Helenius, before returning three and a half years later to blast out Ron Aubrey in one round.
More than a year then past before Peter lined up another fight, although the veteran is now looking at further time out as question marks over his career continue to raise their heads.
Ustinov, 39, will plough on with his fight after drafting in American Alonzo Butler as a replacement for what will be the big Russian’s third fight of 2015.
‘Alexander the Great’ has won five on the spin since suffering his solitary career loss to Kubrat Pulev in 2012 and is hoping to land a world title shot in the New Year.
Opponent Butler has lost three of his last seven bouts in highly questionable company and shouldn’t provide any problems for Ustinov in front of his home crowd at the VTB Arena.
