Wayne Barnes, the referee who red carded Peter O'Mahony in Ireland's opening Six Nations defeat to Wales, will take charge of Munster's Heineken European Championship Cup game against Toulouse at Thomond Park on April 3rd. 

The English official gave O'Mahony his marching orders after 14 minutes of Ireland's 21-16 loss
for his attempted clearout on Welsh prop Tom Francis.
