Rolland is expected to be fit to perform his other match official duties
Alain Rolland has been forced to withdraw from his appointment as Assistant Referee for the RBS 6 Nations match between Italy and England in Rome on February 11 due to a calf muscle strain.
The Irishman, who refereed the Rugby World Cup 2007 Final and a semi-final at Rugby World Cup 2011, will be replaced by fellow countryman George Clancy. The match will be refereed by Jerome Garces on what will be his RBS 6 Nations debut.
Rolland is expected to be fully fit in time to referee France v England in Paris on March 11 and Italy v Scotland in Rome on March 17.
