The Corkman's alleged kick on the Ulster fullback has got him in hot water.

Donncha O'Callaghan was in inspirational form for Munster as they beat Ulster 21-20 in the Guinness Pro12 at the weekend. The 35-year old was his usual annoying self on the pitch and fairly colourful off it, judging by his post match comments. However, he won't be feeling too chirpy today after match citing commissioner Eddie Walsh cited him for an incident with Ulster full back Stuart Olding in the first minute of the second half. The Munster captain is alleged to have kicked Olding in the head with his boot and the Ulster man had to undergo a Head Injury Assessment before getting back on the pitch. The hearing will be held midweek and O'Callaghan could face a ban if found guilty. HT to Munster Rugby
