IRFU Chief Executive Philip Browne has issued a statement following confirmation of Ronan O'Gara's decision to retire from playing professional rugby.
Broadcast partners BBC Wales and TG4 have followed up the decision by Tournament Director Keith Grainger to get all games to kick-off at the same time on Friday night by arranging to swap highlights as their live matches are played.
BBC Wales will be at Stradey Park for the clash of the top two teams, Llanelli Scarlets and Ulster, while TG4 will be broadcasting the match between the inaugural champions Leinster Lions and third placed Newport Gwent Dragons at Lansdowne Road.
Llanelli Scarlets hold a one-point advantage over Ulster and The Dragons going into the last round, and while most fans think the mouth-watering Scarlets-Ulster clash at Stradey Park on Friday night will decide the title, The Dragons have won more games than any other side in this year's tournament and cannot be discounted.
"We know there are going to be some nervous moments for the players and fans of all three teams chasing the Celtic League title and we don't want our viewers to miss a moment of the drama," said BBC Wales Head of Sport, Nigel Walker.
"We couldn't have scripted a more thrilling finish to the league and we want to ensure we capture every second of the action. We will be starting our coverage at Stradey Park, picking up crucial highlights of the game involving The Dragons in Dublin and also keeping in touch with the Neath-Swansea Ospreys game in Glasgow.
"The quality of the rugby in this competition over the past month has been fantastic and the crowds, and our viewing figures, have been above average. That shows there is still a huge demand for competitive rugby action in Wales."
As well as the title, Welsh fans have more than a small interest in two other matches this week, with relegation from next season's Heineken Cup hanging over the Cardiff Blues or the Neath-Swansea Ospreys. The bottom-placed Welsh region will lose their Cup spot and the battle to avoid the drop is almost as close as the one to win the title. The Blues are three points behind the Ospreys and need a big win over Edinburgh on Thursday night. They then need Glasgow to do them a favour by beating the Ospreys 24 hours later.
Throw in the fact that legendary Welsh fly-half Neil Jenkins plays his last competitive match when the Celtic Warriors travel to Connacht on Friday night, and this is easily the most exciting round of an enthralling home-and-away Celtic League tournament.
