Dragons new head coach Dean Ryan has described this afternoon’s Guinness PRO14 visit to Thomond Park as “a massive challenge”. His forwards coach, Ceri Jones, went a stage further in calling it “the acid test”.

A raucous Sportsground welcomed Connacht’s progression into the play-off stages of the PRO14 as their team turned in a bonus point performance in their most important game of the season so far.

Michael Bradley spent most of his seven years at the Sportsground not just wondering if he would be in a job at the end of the season, but rather whether the Connacht team he was coaching would still be in existence.

Joey Carbery may not be happy to take the late hits but if it frees up a teammate then he will continue to endure the pain for the Munster cause.

Tonight will tell Stuart Lancaster a lot.

Beauden, Jordie, and Scott Barrett will become the first trio of brothers to start a Test together for the All Blacks when they line up in the series-opener against France at Auckland’s Eden Park on Saturday.

Ulster 35 Ospreys 17: So after a season where more headlines were made off the pitch rather than on it, Ulster, the 1999 Heineken Cup kingpins and forerunners of Ireland’s glorious history in the competition, will still have a place at the top table of European rugby next season.

The loss of inspirational skipper Rory Best for tomorrow afternoon’s PRO14 shoot-out against the Ospreys at the Kingspan Stadium (kick-off, 3.05pm) will hit Ulster hard, particularly with Ireland lock Iain Henderson also sidelined.

Connacht’s slim Champions Cup qualification hopes were ended in Swansea as Kieran Keane’s side were beaten 39-10 by the Ospreys.

OSPREYS 32 LEINSTER 18: Leinster limped back into Dublin late on Saturday night having fluffed their lines in their dress-rehearsal for the Champions Cup quarter-final with Saracens and licking their wounds after a mauling by the Ospreys.

If you are going to make changes in the aftermath of a crushing defeat you would be advised to have a few British & Irish Lions hanging around the place looking for some game time and that is just the luxury Rassie Erasmus has at his disposal this afternoon.

Connacht lacked so much ‘attitude and commitment’ according to coach Kieran Keane who bristled with frustration as his side lost for the third time in four PRO14 games on Saturday.

Connacht have turned to new out-half Andrew Deegan as they seek a crucial home win against Cardiff Blues.

In the end the margin of victory was just five points, but Munster were the dominant force at the Liberty Stadium as they made it three straight Guinness Pro14 wins.

Munster face their first serious test of the new season when they travel to Swansea’s Liberty Stadium todayto face the Ospreys in the third round of the Guinness PRO14.

Leo Cullen has warned that Leinster cannot allow their upcoming South African trip to distract them from the business at hand tonight when they face Cardiff Blues at the RDS in the second round of the Guinness PRO14.

Just one week after proving to all of Europe how dangerous he is in the No 15 shirt, Joey Carbery is back to orchestrate another Leinster victory, only this time he will be wearing number 10.

Here’s the lowdown on four big games across Europe...

Leinster 31 Ospreys 19: Watching Leinster sure ain’t dull this season.

Leinster will hope that a seasonal debut for Jonathan Sexton can inspire a more consistent 80-minute performance tonight as they welcome Guinness PRO12 table-toppers Ospreys to the RDS.

Only once before have Connacht lost their opening two league matches at the Sportsground but Pat Lam appreciates they must show significant improvement to prevent that happening again when Ospreys come to Galway this evening (7.35pm).

Leinster 19 Ospreys 16: The view from the Leinster coaching box was this margin of victory should never have been so tight, but such is the strength of the Guinness PRO12 right now they can expect much of the same from here on in.

Jonathan Sexton won his fly-half battle with Dan Biggar to help send Leinster to the top of the Guinness Pro12 table with victory over the Ospreys at the Liberty Stadium.

Youth fills in for experience when Connacht try to halt an 11-year losing run in Wales to the Ospreys.

Munster head coach Anthony Foley will unleash his southern hemisphere imports on the Ospreys at the Liberty Stadium tomorrow, naming Aussie second row Mark Chisholm and New Zealand backs Tyler Bleyendaal and Francis Saili in the side for a crucial Guinness Pro12 clash.

A disastrous start left Ireland with an impossible task when they fell 19-0 behind after just 15 minutes at Stadio Zaffanella last night.

In a big day for Irish teams in the Guinness Pro12, Connacht’s needs are probably greater than the rest.

Ospreys 26, Munster 12: Anthony Foley was left scratching his head after seeing his Munster side blow the chance to return to the top of the Pro12.

Ospreys v Munster

For the second game in succession, Leinster coach Matt O’Connor has opted to make seven changes to his starting line-up.

If there is one person Ulster have missed more than any other during an injury-plagued 2014, it has been their cultured scrum-half Ruan Pienaar.
