This week-end Saturday Sport With John Kenny is once again extended at both ends on Long wave 252 and Medium wave 567 to accommodate the Leinster and Munster Heineken Cup ties, but this time there's the added bonus of Connacht's Challenge Cup second leg tie against Grenoble.
Munster are away to Harlequins at 1.00pm and amongst the record breaking crowd at Twickenham will be Michael Corcoran and Munster of course need to win and then hope to get a home quarterfinal.
The Leinster v Treviso game kicks off at 5.15 and Marty Morrisey and Conor McGuinness will be describing the action at Lansdowne Road.
Meanwhile at the Sportsground Connacht will have a five-point advantage as they start the second leg of their Challenge Cup quarter-final against Grenoble. That game kicks off at 2.00pm and will be watched by Gary Moran and Joe Healy.
From 2.00pm till 6.00pm the programme will be on FM as well.
On Sunday Michael Corcoran is travelling to Cardiff to take in Ulster's final pool game against Cardiff.
That starts at 3.00pm and Sunday Sport with Adrian Eames (2.00-4.00pm) will be staying on LW and MW to get the finish of that game and to convey news of the other pool games that will determine the final list of quarter final qualifiers.
