Watch: Peter O'Mahony Sees Red Against Wales

Ireland flanker Peter O'Mahony was given his marching orders by Wayne Barnes after a dangerous clearance at ruck time.

The loose forward, who plays his club rugby for Munster, was deemed to strike Welsh prop Tomas Francis in the head with his shoulder and was sent off just 13 minutes into the Six Nations game against Wales.

It is O'Mahony's third red card in his 74 appearances for Ireland and Ireland's first in the Six Nations.
