If you're a rugby fan, then you'll need to book a place at the bar or a spot on the couch for several hours on Saturday as all three Irish provinces are in action. Munster travel to take on Saracens, and have a tough task to get out of their group ahead of them, as they will have to do so without the services of scrum half Conor Murray, who has been ruled out of their last two European Champions Cup games. They got the better of Saracens last time out, but thanks to two early losses in their campaign, they now have to leapfrog the English side if they are to progress. (BT Sports 1: 12.30pm. Kick off 1.00pm.)

Ulster sit bottom of their group with almost no chance of making it out of the group and face a very difficult trip to Touolon, which kicks off at 3.15pm, while as the day draws to a close, Leinster take on Castres at the RDS. Jimmy Goperth has been handed a start at outhalf by coach Matt O'Connor, with Madigan moving to inside center, while Marty Moore will also start at tighthead. (Sky Sports 1, 5.15 pm. Kick off 5.30pm)
