Welsh referee Nigel Owens will again take charge when Munster face Saracens in their upcoming Heineken Cup semi-final showdown.

Owens was the man in the middle for Munster's epic quarter-final win at Gloucester earlier this month and has been handed his first European semi-final for the meeting of Declan Kidney's and Alan Gaffney's sides at the Ricoh Arena.

And fresh from officiating at Saturday's Anglo-Welsh final at Twickenham, Alain Rolland has been appointed referee for the other semi-final between London Irish and Toulouse.
